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

Find a textbook with a description of microwave cavities.
And yes, this is a very wellstudied 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.
