New and efficient modeling for telecommunication devices

With the collaboration of the CNES, a new modeling method for telecommunication devices, presented in this article, has been implemented on any computer. This method combines the variational method, based on electric equivalent circuit representations, and the boundary element method. Results are successfully compared to measurements and those from the previous publications. © 2002 Wiley Periodicals, Inc. Int J RF and Microwave CAE 12: 247–258, 2002.
