| Abstract: | An extension of the method of causal differential media is given. The present approach makes use of the concept of the generalized extinction cross section of inclusion in a lossy medium to evaluate the total effect of losses, and then resorts to the Kramers—Kronig relations to find the phase velocity. Numerical results and comparison with alternative theories are given. |
