Experience in formulating numerical schemes for solving Maxwells equations. By using Maple, I'm able to start from analytical equations like those of Maxwell and use some symbolic integrals and at the end do the numerical analysis by FEM. Experience in designing Experience with finite differences, finite elements, moment methods and/or Greens functions. FEM is a popular one for solving such problems. These equations are used to show that light is an electromagnetic wave. HFSS uses to solve the equations of electrodynamics, the finite element method (Finite Element Method, FEM), which includes adaptive generation and division of cells. Theory analysis and numerical solution of the Maxwell's equations is a hot topic in both numerical mathematics and engineering communities. And other major concern with the parameters in the design of electromagnetic shielding is very suitable for ;whereas the HFSS uses is based on the theory of finite element method ( FEM ) ,this is a kind of differential equation Method ,the solution is the frequency domain . The Basic governing equation are the well known Maxwells equation which gives the magnetic field in terms of a Magentic Diffusion equation given as: dB/dt = 1/(sigma*mu)*(del^2(B)) --------------- (1) . For both formulations we utilize the finite element method. A boundary value problem where Maxwell's equations of the magnetostatic problem are coupled with the non-linear constitutive behavior is solved using finite element analysis. To effectively The first of these, the finite-difference time-domain ( FDTD) method, is based on the Yee algorithm [12] and uses finite difference approximations of the time and space derivatives of Maxwell's curl equations to create a discrete three-dimensional representation of the electric and magnetic fields. Finite element method for electromagnetics : antennas, microwave circuits, and scattering applications. Notably ,MWS uses is based on the theory of FIT ( finite integration technique ) and FDTD ( finite difference time domain method ) is similar ,it is derived directly from the Maxwell equation solution. COMSOL Multiphysics (formerly FEMLAB) is a finite element analysis, solver and Simulation software package for various physics and engineering applications, especially coupled phenomena, or multiphysics. In electromagnetism, Maxwell's equations are a set of four partial differential equations that describe the properties of the electric and magnetic fields and relate them to their sources, charge density and current density. An axisymmetric finite element method (FEM) model was employed to demonstrate important techniques used in the design of antennas for hepatic microwave ablation (MWA).
