A Simple Asymmetric Resonant Cavity - Greg Egan

"This web page analyses an extremely simple example of an asymmetric resonant cavity: a tapered quadrilateral in two dimensions. The analysis demonstrates that the net force on the cavity walls is zero, providing a simple counterexample to the absurd claim by the British engineer Roger Shawyer [2] that closing off the ends of a tapered waveguide will produce a cavity that can experience a net force from internal radiation pressure (a claim, sadly, much hyped by the magazine New Scientist [1])."
