摘要
对电磁波在包含各向异性媒质多层介质中的传播进行分析，给出了闭合形式的解．该结构可用作法拉第旋转器，与其它准光元件组合构成准光环行器或隔离器．也可用作辐射口径，通过改变磁化场方向和强度实现波束扫描或极化变化．
An analysis of electromagnetic wave propagation in multilayer mediums containing anisotropic material and a closed form representation of the electromagnetic field over the anisotropic region were presented.This structure can be used as a quasi optical Faraday rotator and as either an isolator or circulator when combined with other guasi optical components.It also can be used as a radiation aperture to realize the beam scanning or change of polarization by means of changing the direction and strength of the biased magnetic field.The calculated and experimental results of Faraday rotation were given.
