Ray tracing in Rochon prisms with absorption

We theoretically analyze inhomogeneous plane waves propagating in a Rochon prism made from uniaxial absorbing material. Expressions for the propagation and attenuation directions of the ordinary and the extraordinary waves in the lossy Rochon prism are derived by complex ray-tracing method. As an application, the propagation characteristic of the inhomogeneous plane waves within the lossy Rochon prisms at normal incidence are analyzed and discussed.
