Mode Coupling in Plasmonic Heterodimers Probed with Electron Energy Loss Spectroscopy

Jürgen Brugger, Duncan Thomas Lindsay Alexander, Olivier Martin, Valentin Flauraud, Jérémy Butet, Gabriel David Bernasconi

While plasmonic antennas composed of building blocks made of the same material have been thoroughly studied, recent investigations have highlighted the unique opportunities enabled by making compositionally asymmetric plasmonic systems. So far, mainly hete ...

Mixed-Potential Integral Equation for Full-Wave Modeling of Grounding Systems Buried in a Lossy Multilayer Stratified Ground

Farhad Rachidi-Haeri, Hamidreza Karami, Keyhan Sheshyekani

The paperpresents a comprehensive approach for full-wave modeling of grounding systems buried in a multilayer stratified ground. The dyadic spectral domain Green's function associated with the multilayer stratified ground is first derived. This Green's fun ...

An Optimization Based Coupling Method For Multiscale Problems

Orane Pouchon, Assyr Abdulle, Alexander Shapeev

A new multiscale coupling method is proposed for elliptic problems with highly oscillatory coefficients with a continuum of scales in a subset of the computational domain and scale separation in complementary regions of the computational domain. A disconti ...

Analysis of lightning electromagnetic field propagation in mountainous terrain and its effects on ToA-based lightning location systems

Marcos Rubinstein, Mohammad Azadifar, Farhad Rachidi-Haeri, Zhaoyang Wang, Keyhan Sheshyekani, Dongshuai Li, Qilin Zhang

In this paper, we analyze the propagation effects on lightning-radiated electromagnetic fields over mountainous terrain by using a three-dimensional (3-D) finite difference time domain (FDTD) method. We also discuss the time delay error in the time-of-arri ...
