Simulation of HPM Environment of Electrically Super-large Platforms Using HF Asymptotic Methods

A typical surface ship is an electrically super-large platform for the microwave band, together with lots of complex structures such as upper deckhouses and mast antennas and so on. Thus, the high-accuracy full-wave methods either don’t work or need extremely high calculation resources. To alleviate this problem, the high-frequency asymptotic methods are very attractive due to its high efficiency as well as low storage requirement. In this paper, an effective-work approach based on the radiation equivalent source and the asymptotic methods, is outlined and validated by comparing to the full-wave method.
