Diffraction of an electromagnetic pulse at a finite-length dielectric gradient cylinder

Effects accompanying the propagation of an electromagnetic pulse with a nanosecond edge length in a finite-length dielectric gradient circular cylinder are studied within a three-dimensional model based on Maxwell??s equations. The pulse-edge length is commensurate with the dimensions of the dielectric body being considered. The effect of the direction of electric-vector polarization on the distribution of regions of electric-field enhancement is explored. The effect of the dielectric-cylinder length on special features of the formation of electric fields both within the body and in the surrounding medium is considered.
