Propagation of a coherent electromagnetic wave in a medium with cylindrical pores

摘要

The optical characteristics of a medium with cylindrical pores are investigated theoretically by using the effective refractive index which is found from the dispersion equation for an infinite medium. In frame of quasi-crystal approximation the dispersion equations are obtained for the wave vector of a coherent electromagnetic wave propagating in a media which contains a random set of parallel overlapping cylinders. It is shown that the spectral characteristics of porous medium depend on the regularity in pores placement.
