06_Eigenmode SolverEigenmode SolverDr. Jia Baofu, University of Electronic Science and Technology of China1-1 Overview of Eigenmode SolverEigenmode Solver is used to calculate the resonant frequency of a lossless structural system without open boundaries and the electromagnetic field mode (eigenmode) corresponding to the frequency. The electromagnetic field eigenmode and resonant frequency are the solutions of the following eigen equation. 1-2 Areas of application electromagnetic field distributions of modes at various frequencies Structure design by using the optimizer or the parameter sweep1-3 Solver Setting1. Set units 2. Set background material 3. Define structure 4. Set frequency range 5. Set boundary conditions 6. Start eigenmode solver 7. Analyze results (field patterns, frequencies, losses/Q-factors)1-4 Example 2, Cavity1-5 1-6 Modal Analysis ComputationsThe modal analysis works in combination with the eigenmode solver and calculates Sparameters. However, in contrast to the transient solver, the method is limited to wave guide ports and can not currently handle discrete ports. Compared to the ca……
