Validation of Vibrating Intrinsic Reverberation Chamber using Computational Electromagnetics

2019 Joint International Symposium on Electromagnetic Compatibility, Sapporo and Asia-Pacific International Symposium on Electromagnetic Compatibility (EMC Sapporo/APEMC), 2019
Our study demonstrates a validation of the computational electromagnetics modeling and a simulation of a vibrating intrinsic reverberation chamber (VIRC). The VIRC generates a random electromagnetic environment by shaking the flexible conductive walls to

New Trends in Computational Electromagnetics

New Trends in Computational Electromagnetics, 2019
Electromagnetics is based on the study of Maxwell's equations, which are the result of the seminal work of James Clerk Maxwell completed in 1865, after his presentation to the British Royal Society in 1864. It has been over 150 years ago now, and this is

Investigation of Appropriate Wavelets for Computational Electromagnetics Problems

2018 International Workshop on Computing, Electromagnetics, and Machine Intelligence (CEMi), 2018
In this paper, we have identified the Haar wavelet as the appropriate wavelet for the solution of a class of computational electromagnetics (CEM) problems. In the literature, wavelets were used in the context of efficient and fast computation methods for

Quantum Computational Electromagnetics

2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020
We investigate quantum information preserving computational electromagnetics. To do so, we propose two different methods which are (1) numerical canonical quantization and (2) quantum finite-difference time-domain scheme. The proposed algorithms find numerical solutions of quantum Maxwell’s equations involved in arbitrary inhomogeneous dielectric media

Scalable electromagnetic scattering computations

IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2001
Abstract : In this paper, we summarize the results of our efforts in developing a scalable distributed memory fast electromagnetic integral equation solver. The massively parallel scattering code, called LSSP, is based on a Galerkin discretization of the combined field integral equation (CFIE) using the RWG basis functions.

Computational quantum electromagnetics: A future pathway for computational electromagnetics

2017 IEEE International Conference on Computational Electromagnetics (ICCEM), 2017
First, we emphasize the importance of Maxwell's equations (1865) [1] which have withstood the test of length scales, special relativity (1905) [2], and quantum theory (1927) [3]. Moreover, a differential geometry description of Maxwell's equations (1945) [4] had inspired the Yang-Mills theory (1954) [5], also known as the generalized electromagnetic ...

Computation of Local Electromagnetic Force

IEEE Transactions on Magnetics, 2010
Total electromagnetic force on a body can be predicted by replacing the magnetization and polarization with appropriate equivalent currents and charges. Still, the equivalence of total force does not imply that the integrated densities have physical meaning.
