  In our laboratory, we are working on emission and detection of high
 frequency electromagnetic waves know as terahertz (THz) waves and their
 industrial and biomedical applications. Terahertz wave also known as T-
 ray bridges the frontiers between the microwave and infrared regions of
 electromagnetic spectrum. This range was also known as terahertz gap
 until recently owing to the lack of efficient THz wave sources and
 detectors. However, recent development of optoelectronics and laser
 technology has enabled the efficient emission and ultrasensitive
 detection of broadband THz waves. These waves have excellent
 characteristics such as (a) sensitive to water (b) moderate
 transmittance through various materials such as plastics, paper,
 ceramics etc. and (c) various substances have unique absorption features
 know as spectral fingerprint in THz frequency region. Because of such
 characteristics, THz waves have widely been used in various applications
 such as drug identification, cancer detection, moisture content
 measurement, non-destructive testing and evaluation of industrial
 products and ultra-high speed wireless data transfer. In our laboratory,
 we are working on the following research topics:

 1. Development of 3D terahertz wave computed tomography system :
 Here, we are trying to develop a computationally efficient 3D THz wave
 computed tomography system for the non-destructive testing and analysis
 of industrial products such as ceramics and plastics. For further
 details, please refer: S. R. Tripathi et al., Terahertz wave three-
 dimensional computed tomography based on injection-seeded terahertz wave
 parametric emitter and detector, Optics Express, vol. 24, pp. 6433-6440

 2. Investigation on THz wave interaction with human being:
 Under this topic, we are investigating the role of human sweat ducts in
 interaction of THz wave with human skin. Further details can be obtained
 from: S. R. Tripathi et al., Morphology of human sweat ducts observed by
 optical coherence tomography and their frequency of resonance in the
 terahertz frequency region, Scientific Reports, vol. 5, No. 9071 (2015)

 3. Development of terahertz time domain spectroscopy :
 We are developing THz wave time domain spectroscopic measurement system
 (THz-TDS) in the different configuration for the characterization of
 wide variety of materials in frequency range from 100 GHz to 3 THz. For
 example: S. R. Tripathi et al., Measurement of chloride ion
 concentration in concrete structures using terahertz time domain
 spectroscopy (THz-TDS), Corrosion Science, vol. 62, pp. 5-10 (2012)

  Dr. Chandler's research area is perceptual image and video processing.
 His research focuses on studying how the human visual system interprets
 images and video, and how to use the resulting models to improve
 multimedia applications. He currently heads the Laboratory of
 Computational Perception and Image Quality at Shizuoka University. His
 lab studies a variety of topics on image/video processing, quality
 assessment, and compression; as well as topics on visual psychophysics
 and natural scene statistics.

  大学院総合科学技術研究科 工学専攻 電子物質科学コース Daniel Moraru

  I have joined the Department of Electronics and Materials Science
 since January 2015 as an Associate Professor. I’m originally from
 Romania and graduated from the Faculty of Physics in Al. I. Cuza
 University, Iasi in 2003. I then joined Shizuoka University as a PhD
 student in the Group of Prof. Michiharu Tabe (Research Institute of
 Electronics). For many years even after my graduation, we continued to
 work together on the topic of “silicon dopant-atom electronics”,
 through which we hope to demonstrate atomic-level functionality for
 future generations of electronics.
  The high performance of our present-day computers is due to the fact
 that, nowadays, electronics building blocks - transistors - can be made
 in nanoscale (~10 nm). In the future, as an ultimate goal for low power
 consumption and advanced functionality, we can foresee a world in which
 the operation bits are triggered by single electrons stored in single
 atoms: “single-electron single-atom electronics”. In this direction,
 our group continues to contribute to the field of “silicon dopant-atom
 electronics”. Recently, we focus on analyzing, designing, fabricating
 and characterizing nanoscale silicon devices (transistors and diodes)
 that prominently exhibit atomic- and molecular-level behavior.
  As a core concept, a single dopant-atom (impurity atom) replacing a Si
 atom in a nanostructure can work as a quantum dot with the ability to
 capture and/or transport electrons one by one. This is labeled as a
 single-dopant-atom transistor. Such a simple concept can have complex
 and extended applications due to the possibility of coupling a small
 number of dopant-atoms in a variety of ways. Ultimately, we aim at
 outlining a field of research based on which atomic-level quantum-
 mechanical operation can become the norm for next-generation electronics,
 leading to an ultimately efficient use of the world’s energy resources.
 Relying on Japan’s long and successful history in pushing the limits in
 electronics, we will also strive in our own research to reach such
 ultimate goals.

  Photosynthetic microorganisms have great potential for the sustainable
 production of biofuels and other valuable products. My research focuses
 on using a synthetic biology approach to engineer such organisms to
 increase bioprocess viability. For example, developing novel genetic
 tools to improve the efficiency of the harvesting and product extraction
 steps of a bioprocess, as well as methods to effectively regulate these
 tools. These advances are expected to lead to a truly sustainable and
 viable bioindustry based on photosynthetic microorganisms.

 大学院総合科学技術研究科 工学専攻 数理システム工学コース Guo-jie Jason Gao

  Granular materials are particulate systems such as sands and powders
 that can be found almost everywhere in our daily life. Except liquids,
 granular materials are the second-most manipulated media in industry.
 Since the grains are large, thermal fluctuations cannot induce grain
 rearrangements, and these systems cannot be described by equilibrium
 thermal dynamics. Without external excitations, granular materials
 remain static. However, sufficiently large external driving forces can
 lead to grain rearrangements and fluctuations in physical quantities
 including stress and pressure, as in systems in thermal equilibrium.
  Our group develops molecular dynamics (MD) and Monte Carlo (MC)
 algorithms to understand the behavior of dry (ignoring the interaction
 between a grain and its surrounding gas or liquid) granular materials
 under various conditions. MD is a computer simulation method for tracing
 the physical movements of N particles by solving the Newton’s laws of
 motion (F = ma) between any two particles, interacting via a predefined
 interparticle potential. On the other hand, movements of particles in
 MC simulation are governed by a given probability function and therefore
 are indeterministic.
  Implementing the above numerical approaches, we tackle several
 interesting scientific problems in engineering and biology with
 significant industrial impacts: (a) analyzing the hopper flow through a
 nozzle dispensing metallic powder in a 3D printer, which makes solid
 objects of virtually any shape, and (b) clarifying the chaining behavior
 observed in the initial phase of invagination process in a fruit fly
