RIGOROUS ANALYSIS OF 3-DIMENSIONAL STRUCTURES INCORPORATING DIELECTRICS

This paper presents the SR3D software (3-D radiating structures), whic h calculates the electromagnetic characteristics of arbitrarily shaped structures incorporating dielectric material. The rigorous analysis m ethod is based on the integral equation formulation. We included a var iational approach using the reaction concept of Rumsey. The problem is numerically solved with a surface finite elements method. A guided mo de excitation has been introduced in order to compute the reflection c oefficient at the transmit port and the transmission coefficient betwe en the different parts fed by guided modes. This software is validated by excellent agreement between simulated and measured radioelectric p erformances (patterns and SWR).
