Abstract
AN ALGORITHM IS DEVELOPED FOR APPLICATION IN A RAY TRACING PROGRAM TO PROVIDE THE AMPLITUDE, POLARIZATION, AND PHASE OF AN ELECTROMAGNETIC WAVE REFLECTED FROM A DIELECTRIC BODY. TWO DIFFERENT CONFIGURATIONS ARE USED. THE FIRST CONSISTS OF AN ABSORPTIVE DIELECTRIC BODY AND THE SECOND OF A DIELECTRIC BODY COATED WITH A ABSORPTIVE LAYER. THE ALGORITHM IS BASED ON AN EXACT SOLUTION TO THE BOUNDARY VALUE PROBLEM DEFINED BY THE CONTINUITY OF COMPONENTS OF THE ELECTRIC AND MAGNETIC FIELDS ACROSS THE BOUNDARY. THE REFLECTIVITY FROM THE ABSORPTIVE COATING IS CALCULATED USING FINITE VECTOR SUM DEVELOPMENT OF THE MULTIPLY REFLECTED ENERGY IN THE ABSORPTIVE LAYER. EXAMPLES OF THE DISPERSIVE EFFECTS OF THE ABSORPTIVE LAYER ARE MODELED FOR SOME REPRESENTATIVE INPUT SIGNAL IMPLUSES. DETAILED EXAMPLES OF VARIOUS ALTERATIONS IN THE REFECTED SIGNAL PARAMETERS DUE TO THE NATURE OF THE SURFACE WILL BE ILLUSTRATED IN THE FINAL REPORT.
