FDTD and TLM are time domain techniques, which have been used for more than a decade. MoM is a frequency domain technique and has been used for nearly thirty years. All three techniques are widely used and well understood. Therefore, only some of their practical aspects are mentioned in this section.

Here, three well-known techniques, FDTD, TLM and MoM, are reviewed and applied to variety of important EM problems. Each EM problem is handled via one or two of these techniques so that the results can be compared with each other. The examples presented are listed below together with the most suitable numerical techniques as applications:

Waveguide analysis (FDTD and TLM)

EMC/EMI Modeling (FDTD and TLM)

Cellular phone–human head interaction in terms of biomedical effects and antenna performance (FDTD)

RCS Modeling (FDTD and MoM)

Except other FDTD method is very efficient and good for modelling. It does modelling simulations by using different ways. In previous dates, there are too many different simulation techniques in FDTD. We can classify these methods as;

Dimension of Simulation Type of Material

One-dimensional Free space

Two-dimensional Dielectric material

Three-dimensional Lossy dielectric material

Frequency-dependent material

At the beginning we fork for learning basical induction of FDTD and its mathematical expression. After we applied some rules for abc,pml and begin to programming in MATLAB.

FEM

The finite element method of structural analysis was created by academic and industrial researchers during the 1950s and 1960s.The finite element method is originally developed to study stresses in complex aircraft structures. Then is applied to other fields of continuum mechanics, such as heat transfer, fluid mechanics, electromagnetics, geomechenics, biomechanics.

The finite element method (FEM) and its hybrid versions (finite element-boundary integral, finite element-absorbing boundary condition, finitie element-mode matching, etc.) is one of the most successful frequency domain computational methods for low and high frequency electromagnetic simulations. From its earlier introduction for electrical machine modeling, its applications now cover antennas, microwave circuits, propagation and large scale scattering from non-metallic structures.
