“…Solving (1) by using MoM, the whole structure is discretized into small segments/triangles. J W and J S are then expanded by using the RWG basic functions defined on each pair of segments/triangles [13][14][15]. In this way, by using Galerkin testing method, we can obtain the following linear equations…”

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.

“…(The wave impedance in the good conductor equals η 0 η s ≈ ωµ iσ [21]. Thus the EFIE with IBC approximation in [18,22] will be degenerated to (4).) However, it is straightforwardly derived from the volume integral equation, and is used in solving for the quasistatic inductance extraction problems here.…”

“…Here we call it the finite conductivity surface integral equation (FCSIE). Though the FCSIE is derived from the Volume Integral Equation, it is similar to the Electric Field Integral Equation Method (EFIE) with Impedance Boundary Condition (IBC) Approximations that is always used in solving the EM scattering problems [18,19]. However, here we use it for quasistatic inductance extraction problems.…”

Abstract-In this paper, we consider the resistances and inductances extraction from finite conducting metals. To remedy the weakness of volume integral equation, we extend the usage of a surface integral equation method from analyzing finite conducting rectangular wire strip to analyzing arbitrarily shaped geometry. Moreover the multilevel Green function method (MLGFIM) with a complexity of O(N ) is employed to accelerate the matrix-vector multiplications in iterations. The numerical results shows the efficacy of the proposed method.

“…This impedance relates the external, tangential electric and magnetic field at the boundary of the object under study by a function that depends on the material's properties, as such eliminating the need to solve the internal field problem. Various methods exist [3] of which the Leontovich boundary condition is the most widely employed [4]. However, despite its versatility, the surface impedance formulation has a limited range of validity [5].…”

Abstract-This paper presents a novel approach to simulate materials with arbitrary properties, in particular good conductors, in a boundary integral equation (BIE) context. The advocated differential surface admittance operator permits the replacement of the material by the background medium through the introduction of an equivalent surface current density. A formulation based on the eigenfunctions of the volume is constructed and successfully demonstrated through scattering at a conducting cylinder and through the analysis of a lossy dipole antenna.
