WebDec 30, 2024 · Therefore, we will first review some background information about Maxwell’s equations and the finite element method. 2 Basic Forms of Equations to Be Solved in Electromagnetics. The aim of electromagnetics modeling is to solve Maxwell’s equations subject to certain boundary conditions. Maxwell’s equations in their differential form … WebJun 21, 2024 · The fields of Equations ( 12.5.7) and ( 12.5.8) satisfy Maxwell’s equations. They must also satisfy the boundary conditions E θ =0, E z =0, and H r =0 at the walls of the wave-guide. Let the inner radius of the wave-guide be R meters. The boundary conditions can be met if J m (k c R)=0.
