Recent advances in computational electromagnetic tools made antenna design possible along with integration of antennas on various ground, sea and air platforms. Full wave techniques such as Method of Moments (MoM), Multilevel Fast Multipole Method (MLFMM) along with asymptotic techniques such as Physical Optics (PO) and Uniform Theory of Diffraction (UTD) will be reviewed. Application of these and hybrid numerical techniques for antenna designs, antenna-platform interaction studies, EMI/EMC, bio-electromagnetics and Radio Frequency Identifcation (RFID) system design. For many practical applications, sometimes it is necessary to study the electromagnetic behavior on a specific structure over a broad frequency band, and therefore it is important to have some benchmark data on computational resources needed for some commonly used numerical techniques. In this paper, a full-size air, ground and sea platforms are considered and the frequency limit is pushed at different bands using several numerical techniques. A benchmark study of computational resources required by available computational tools for electrically large platforms will be presented.
