Abstract

The problem of accurately predicting the performance of a complex antenna system with a variable-thickness, frequency selective surface radome mounted on an aircraft is a difficult one both theoretically and numerically. The complexity of the antenna system calls for use of a full-wave numerical solver, while the large electrical size of the aircraft calls for use of a high-frequency method. Remcom proposes an innovative solution that combines Remcoms full-wave solver for the antenna system, XFdtd, with Remcoms high-frequency solver for the aircraft surface, XGtd. The coupling between the two solvers will be provided by two innovative interfaces to XFdtd, one for incoming electromagnetic waves and one for outgoing waves. This solution is able to handle the full complexity of the structures and surfaces in the near vicinity of the antenna, while being scalable to electrically large structures. Because XFdtd and XGtd are proven commercial products with established user communities, commercialization of the proposed hybrid combination will satisfy the needs of existing customers for a practical solution for the analysis of antenna systems mounted on electrically large platforms, as well as open new opportunities in the defense, automotive, and telecommunication industries.
