INTERACTION OF ELECTROMAGNETIC IMPULSE WITH ONE-DIMENSIONAL PERIODIC SURFACE. THE CASE OF VERTICALLY POLARIZED ELECTRIC FIELD
The task of Gaussian frequency-modulated electromagnetic impulse scattering from one-dimensional periodic surface in case of vertically polarized electric field is considered. Influence of reflection coefficient R<sub>n</sub>(ω) phase-dependence Ф<sub>n</sub>(ω ) = arg R<sub>n</sub>(ω) character on scattered impulse transformation is analyzed. Dependence Ф<sub>n</sub>(ω) is derived as a result of numerical evaluation by variable order Adams-Bashforth-Moulton method of matrix Riccati equation [1, 2] for reflection coefficient R<sub>n</sub>(ω), which describes plane wave scattering from the considered periodic surface. It is shown that specific relations between task parameters yield electromagnetic impulse compression. Similarity between one-dimensional periodic surfaces and one-dimensional photonic crystals is emphasized.
