An Efficient Hybrid Technique for Analysis of the Electromagnetic Field Distribution Inside a Closed Environment

Abstract

Abstract-This paper presents an efficient hybrid simulation technique for analysis of the electromagnetic field interactions between multi-transmitters and receivers located within a closed environment. The Method of Moments/circuit method is first used for modeling of the transceivers and their nearby surrounding to obtain the equivalent sources/receivers. Then, an approach that combines the asymptotic method and the ray tracing technique is deployed to calculate the long-distance coupling between a pair of transmitter and receiver. The acceleration algorithms for ray tracing have been developed to deal with more complex scenarios. The seamless combination between the circuit, numerical, and asymptotic approaches is the key to get accurate simulation results. Several numerical examples and experimental results are presented to demonstrate the efficiency of the proposed technique.

Analysis of Scattering With Multi-Slotted Cylinder With Thickness: Tm Case

“…Although the problem in determining the electromagnetic scattering from and penetration of conducting cylinders with axial slots has been investigated by many researchers with various techniques [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], the determination of the transmitted field through multi-slotted circular cylinder in a thick conducting shell covered with dielectrics has received little attention. A simplified model of the problem to be solved here is represented by Fig.…”

An approach combining the integral equation method with a generalized image technique for modeling incabin radio wave propagation

“…[1][2][3][4] The ray tracing techniques are generally classified into two categories 3,4 : the shooting-and-bouncing (SBR) technique [5][6][7] and the image-based ray tracing method. [8][9][10][11][12][13] The SBR technique is powerful for complex environments. It introduces a reception sphere with an assumed radius to determine whether a ray is received.…”

Computational Performance of a Weighted Regularized Maxwell Equation Finite Element Formulation

“…Only the three components of E, or H, are the unknowns (there is no need of extra functions such as Lagrange multipliers or scalar potentials [4]). Its integral representation has a singular kernel of order 1 (instead of the order 3 exhibited by the double-curl formulation), which makes the regularized formulation well suited for hybridization with integral numerical techniques [5][6][7][8][9]. The nodal solution of the electromagnetic problem is easy to couple in multiphysics problems (thermal, mechanic,.…”
