Simulation of Beam Propagation with Two-photon Absorption in Semiconductor Materials

Syuhei LEE et al.[1]

[1]Chiba University, Chiba, Chiba, Japan

We have studied ultrafast all-optical switching devices based on two-photon absorption, which are expected to have ultrafast response less than 1 ps in wideband and to be independent of polarization of light. In our laboratory, we have obtained the analytical solution for the equation of ... 詳細を見る

Analysis of the Characteristics of the Terahertz Communication Device by using the COMSOL RF Module and its Complement

Hirokazu YAMAKURA[1]

[1]Tokyo Metropolitan University, Hachioji, Tokyo, Japan

We present simulated examples of analyzing characteristics of terahertz communication devices by using the COMSOL RF module. Especially, we propose a coupled analysis method, which has a mutually complementary relationship between the numerical analysis in the COMSOL and an additional ... 詳細を見る

Interaction between Light Wave and Asymmetric Metal/Insulator/Metal (MM) Structure Coupled with Subwavelength Holes at Optical Fiber Apex

Yasushi OSHIKANE[1]

[1]Osaka University, Suita, Osaka, Japan

Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of ... 詳細を見る

Analysis of Temperature Distribution in a Magnetite Catalyst Bed under Microwave Irradiation using COMSOL Multiphysics®

Dai MOCHIZUKI et al.[1]

Tokyo Institute of Technology, Yokohama, Kanagawa, Japan[1]

Dehydrogenation of ethylbenzene with a magnetite catalyst has been performed with a fixed bed flow type reactor under microwave irradiation. Microwave heating showed a temperature gradient in the catalyst bed. We analyzed an electromagnetic field and heat transfer in the microwave cavity ... 詳細を見る

Chemical Reaction under Highly Precise Microwave Irradiation

Satoshi Fujii et al.[1]

[1]Chiba University, Chiba, Chiba, Japan

Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... 詳細を見る

Calculation in Coupling Coefficient of 1.3μm Quantum Dots Distributed Feed Back Laser with Half Etched Mesa Structure

Keishiro GOSHIMA et al.[1]

[1]Aichi Institute of Technology, Toyota, Aichi, Japan

Quantum Dots (QDs) laser is expected to have a low threshold current density and high thermal stability. We propose the QDs laser with the half-etched mesa distributed feedback (HEM DFB) structure. We accurately calculated the coupling coefficient in a HEM waveguide using the finite ... 詳細を見る

Design of Guide for Avoiding Buckling Fracture of Micro Needle Inspired by Labium of Mosquito

Tomokazu TAKASAKI[1]

[1]Kansai University, Suita, Osaka, Japan

Making a diameter of needle small is effective for reducing the pain of patients. However, thinning a needle leads to easy buckling in the puncturing process, because the aspect ratio of needle becomes high. We propose a method for avoiding buckling of thin needle by setting a guide ... 詳細を見る

Design of Capacitive Vibratory Energy Harvester Calculating Change in Capacitance in Fringe Electric Field and Structural Analysis of Spring

Tomokazu TAKASAKI[1]

[1]Kansai University, Suita, Osaka, Japan

The sensing without batteries can be realized by harvesting the unused energy in environment. The capacitive harvester can generate, since the capacitance between electrodes is changed by vibration. There are two methods of producing change in capacitance: 1) change in overlapped area ... 詳細を見る

Analysis of Optical Manipulation of a Metallic Nanowire using COMSOL Multiphysics®

Ryota OZAWA et al.[1]

[1]Yokohama National University, Yokohama, Kanagawa, Japan

We have developed optically driven micropumps by manipulating microstructures using optical tweezers. In this study, we proposed and developed a novel manipulation method of a single metallic nanowire. In this method, dynamic optical vortex is used not only for manipulating a metallic ... 詳細を見る

Finite-Element Analysis of High Frequency Electromagnetic Fields

Masanori HASHIGUCHI et al.[1]

[1]Keisoku Engineering System Co., Ltd., Chiyoda City, Tokyo, Japan

Using COMSOL Multiphysics, numerical solution of electromagnetic field of microstrip open stub is obtained in frequency domain of 0.1GHz - 60GHz by using the COMSOL RF Module and the computed S11 is compared to experiment. It was found that the S11 predicted here is in good agreement ... 詳細を見る
