Arranged from low to high according to the degree of resolution, they are the finite difference time domain method (FDTD), transmission line method (TLM), finite integration time domain method (FITD), finite element method (FEM), method of moments (MoM), Line Method (ML), Boundary Element Method (BEM), Spectral Domain Method (SM), Mode Matching Method (MM), Transverse Resonance Method (TRM), and Analytical Method.Īccording to the accuracy of the results from high to low, they are an analytical method, semi-analytical method, and numerical method.

Numerical methods are divided into zero-order, first-order, second-order, and higher-order methods. In the time domain, numerical algorithms include Finite Difference Time Domain ( FDTD – Finite Difference Time Domain ), and the finite integral method ( FIT – Finite Integration Technology ).Īmong these methods are analytical, semi-analytical, and numerical methods. In the frequency domain, numerical algorithms include the finite element method (FEM - Finite Element Method), moment method (MoM - Method of Moments), difference method (FDM - Finite Difference Methods), boundary element method (BEM - Boundary Element Method), and transmission line method (TLM - Transmission-Line-matrix Method). There are many different algorithms in computational electromagnetics, such as finite difference in the time domain (FDTD), finite integration in the time domain (FITD), finite element method (FE), method of moments (MoM), boundary element method (BEM), Spectral domain method (SM), transmission line method (TLM), mode matching method (MM), transverse resonance method (TRM), line method (ML) and analytical method, etc.
