All-Plasmonic Thermo-Optic Modulator for GHz Signal Switching at the Metal–Semiconductor Interface

Mayra Schliemann¹, Raj K Vinnakota¹
¹Troy University, Troy, Alabama, USA

The integration of plasmonic components into optoelectronic platforms enables promising pathways for high-speed, ultra-compact signal modulation at the nanoscale. In this work, we present a novel all-plasmonic modulator, which leverages localized surface plasmon resonance (LSPR)-induced ... En savoir plus

Definition of Optimization Problem for Electromagnetic Linear Actuator

P. Piskur[1], W. Tarnowski[1], and K. Just[1]

[1]Koszalin Technical University, Koszalin, Poland

In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be ... En savoir plus

Operation of an Electromagnetic Trigger with a Short-Circuit Ring

D. Križaj[1], Z. Top?agi?[1], B. Drnovšek[1]
[1]Faculty of Electrical Engineering, University of Ljubljana, Ljubljana, Slovenia

Numerical simulation of an electromagnetic trigger with a short-circuit ring is presented. The main goal of inclusion of a short-circuit ring in an electromagnetic trigger is to develop an element suitable for use in a circuit breaker with capabilities of selective switching. The main ...

Electromagnetic Field Computations for Saturated Porous Media

S. Cambon[1], I. Bogdanov[1]
[1]CHLOE, Bâtiment UFR Sciences et Techniques, Pau Cedex, France

Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such ... En savoir plus

Electromagnetic Wave Analysis of Wave And Shielded Stripline

S. Singh[1], A. Marwaha[1]
[1]Department of Electronics and Communication Engineering, Sant Longowal Institute of Engineering Technology Longowal, Punjab, India

Electromagnetic wave analysis of waveguide has been done in this paper with the help of Finite Element Method (FEM) based COMSOL Multiphysics. The design is further extended by placing conductor on a dielectric slab included in the waveguide to form a shielded microstrip transmission ... En savoir plus

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 ... En savoir plus

Electromagnetic Modeling of Field Emitter Cathodes Inside an L-Band RF Gun at Fermilab Using COMSOL®

H. Panuganti [1,2,3], P. Piot [1,3],
[1] Northern Illinois Center for Accelerator and Detector Development (NICADD), Northern Illinois University, DeKalb, IL USA
[2] Department of Mechanical Engineering, Northern Illinois University, DeKalb, IL, USA
[3] Fermi National Accelerator Laboratory (FNAL), Batavia, IL, USA

Field-emitter (FE) electron sources offer significant advantages over photocathode and thermionic sources due to their ability to be operated without the need for an auxiliary laser system or a heating source. While FE cathodes have been traditionally used in DC environments, we explore ... En savoir plus

High-performance and incident angle-tunable terahertz sensing assisted by BIC

邵伟佳¹, 王玉¹
¹广西师范大学

Terahertz (THz) sensing has been attracting interest due to its capabilities for biological fingerprint and medical identification. However, achieving angle-tunable ultrahigh figure-of-merit (FOM) of THz sensing remains challenging due to the difficulty in realizing tunable resonances ... En savoir plus

Electromagnetic Mode Simulation on Optical Fiber Coupling With Transversal Misalignment

P. F. Gomes[1], R. G. e Souza[1], F. Beltrán-Mejía[2], J. L. G. Arango[3]
[1]Universidade Federal de Goiás, Jataí, GO, Brazil
[2]Universidade Estadual de Campinas, Campinas, SP, Brazil
[3]Universidad de Pamplona, Pamplona, Colômbia

We used COMSOL Multiphysics® software to calculate the mode distribution by numerically solving the wave equation in the fiber. We consider the transmission from the fiber 1 to the fiber 2. In the first case, the transmission was calculated as function of the wavelength of the propagated ... En savoir plus
