摘要 本文基于渐近波形估计 (AWE)技术和矩量法 (MOM)快速预测无限大导体平面上任意形状凹槽的散射场方向性函数。用矩量法求解得到给定方向入射波照射下凹槽口径磁流 ,用AWE技术得到任意方向入射波照射下口径磁流 ,进而计算出散射场的方向性函数。计算结果表明AWE能逼近 MOM计算结果 。 The method of moments (MOM) combining with the asymptotic waveform evaluation (AWE) technique is used to predict scattering fields of an arbitrarily shaped groove in a perfectly conducting plane.In MOM,the magnetic current in the aperture irradiated at a given direction by electromagnetic (EM) wave is obtained.In the AWE technique,the magnetic current in the aperture at any angle within the angular range is obtained which is in turn used to calculate the directional function of scattering fields of an groove.It was observed that AWE could result in considerable saving of CPU time.
