RCS Evaluation of Array Antennas Using FDTD Method (Part 1),

Abstract

In this work a method to study the reflection properties of large periodical structures is studied. The study makes use of the Finite Difference Time Domain method and the Floquet theorem in relation with the properties of periodicity of the structure under analysis. The result achieved is the evaluation of the Reflection Coefficient, for perpendicular observation direction, for any kind of infinite periodical structure. The unit element of such a structure can have any shape and can be made of any kind of material (metal or dielectric). An important conclusion can be drawn: when compared, calculated and reference results show a very good agreement. Further developments of the study are aimed to evaluate the Radar Cross Section of large finite periodical structures for any direction of observation.
