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

The numerical approximation of Maxwell's equations, Computational Electromagnetics (CEM), has emerged as a crucial enabling technology for radio-frequency, microwave and wireless engineering. The tumor cell and normal cell are designed as spherical cells. 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. 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) . The ADINA System offers a one-system program for comprehensive finite element analyses of structures, fluids, heat transfer, electromagnetics and multiphysics. So choices that cell designers, designers of some These field solvers create a finite-element mesh through the structure-often in three dimensions-and then solve Maxwell's Equations by successive approximation on the elements of the mesh. The model developed using Maxwell 3D Simulator is shown in Figure 1. The three most popular 'full-wave' methods - the Finite Difference Time Domain Method, the Method of Moments, and the Finite Element Method - are introduced in this book by way of one or two-dimensional problems. The relative advantages of the BEM over the more widely used Finite Element Method (FEM) are that for electric and magnetic fields, the governing equations to be solved are Maxwell's. This is important because errors in extraction at the cell level can become systematic errors in timing analysis, accumulating across a structure rather than averaging out. The ADINA EM module provides capability for solution of the general Maxwell's equations, governing electromagnetic phenomena. The ADINA FSI (fluid structure interaction) program is the leading code used by industries for fully coupled analysis of fluid flow with structural interaction problems.
