## Has path of a standing wave confined in a metal box been measured and described?

Has path of a standing wave confined inside a metal box been measured and described?

I'm thinking path is circular, or, oscillates/bounces back and forth like a pendulum.

I'm thinking of a standing wave moving inside a metal rectangular box.

Has the path of a standing wave inside a rectangular metal box ever been measured and described?

Where can I read this description?

Thanks, bentlight

 Recognitions: Gold Member Science Advisor Find a textbook with a description of microwave cavities. And yes, this is a very well-studied problem (cavities are used in LOTS of applications, especially in microwave systems); and for rectangular cavities (=boxes) the math is actually quite easy.
 In addition to f95toli: a standing wave stands. No back and forth movements. It's like cos(wt)*cos (pi*x/X)*cos (pi*y/Y)*cos(pi*z/Z), if needed with higher modes.
