Simulating e&m wave propagation

Click For Summary

Discussion Overview

The discussion revolves around simulating electromagnetic wave propagation in a cavity, specifically focusing on the introduction of spatially dependent phases between mirrors that support certain transverse modes. Participants explore challenges related to solving for eigenmodes and seek recommendations for suitable simulation software.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses difficulty in simulating a cavity problem and questions the feasibility of solving for eigenmodes.
  • Another participant suggests that programs like Microwave Studio are designed for such simulations and notes their common use in accelerator physics.
  • A participant mentions having looked into Microwave Studio and COMSOL but is unable to find purchasing information on their websites.
  • Another participant provides a link to a resource listing free software options and advises contacting companies directly for pricing on COMSOL and similar products.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach or software for simulating the cavity problem, and multiple viewpoints regarding available tools and their accessibility are presented.

Contextual Notes

Limitations include the lack of specific details on the requirements for the simulation and the dependence on external software availability and pricing information.

Hello everyone.

I'm really struggling to simulate a cavity problem.

My goal is to be able to know what's going to happen if i introduce spatially dependent phase inbetween mirrors of a cavity that supports certain transverse modes.

Well, i believe solving for eigenmodes of a cavity is near impossible.

If you guys know something about this sort of challenge or know any good e&m simulators, could you direct me to it?

Thank you

Aren't programs such as Microwave Studio designed to do just that?

Programs and codes doing this are quite common in accelerator physics, since one has to deal with RF structures all the time, and having fields with different modes. So if you know of any accelerator physics group, those are the people you might want to ask.

i have looked at Microwave Studio and COMSOL.

there websites don't seem to sell them..

do you know where i can purchase these products?
 
I found this link http://www.edaboard.com/thread180440.html a while ago. It lists some free software. If you want COMSOL etc you have to contact the company direct to get a price list. There's normally an online request form and a sales person will contact you.
