Finite Element Methods for Maxwell's Equations Peter Monk
Publisher: Oxford University Press, USA

HFSS uses to solve the equations of electrodynamics, the finite element method (Finite Element Method, FEM), which includes adaptive generation and division of cells. These equations are used to show that light is an electromagnetic wave. Among the most popular ones I can recall here. I have downloaded a free software code, Finite Element Method Magnetics (FEMM) solver (see http://www.femm.info/wiki/Download) but it doesn't work because FEMM is limited to solving low frequency electromagnetic problems on two- dimensional planar and axisymmetric domains. 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. Solutions for the electromagnetic field, found from Maxwell's equations to accurately determine all the characteristics of a microwave device, with the emergence and transformation of some types of waves in the other losses in the materials and the radiation, etc. This form includes time harmonic Maxwell equations, the acoustic equation, and the equations of linear elasticity. John Leonidas Volakis, Arindam Chatterjee & Leo C. 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. Since the middle of the last century, computing power has increased sufficiently that the direct numerical approximation of Maxwell's equations is now an increasingly important tool in science and engineering. 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 . Finite element method for electromagnetics : antennas, microwave circuits, and scattering applications. Maxwell's Equations grad, curl, div. FEMM addresses some limiting cases of Maxwell's equations. Bevy of material on doing Maxwell's Equations. There are many different approaches to solve Maxwell equations in presence of complex objects.
