摘要

从理论上考虑了具有空间振荡参数的阻抗面上波束与面波的耦合现象。所采用的方法对平滑参数是渐近的，对扰动幅值是数值的。它结合了具有大量“周期”的准周期结构的渐近方法和数值方法的优点。得到了谐振谐波复幅值的耦合系数。分析了非互易布拉格现象。

Semiasymptotic method for plane with quasiperiodic spatial perturbation of gyrotropic surface impedance

Phenomena of coupling of wave beams and surface wave at impedance plane with spatially oscillating parameters are theoretically considered. Used method is asymptotic with respect to smoothness parameter and is numerical with respect to perturbation amplitudes. It combinesadvantages of the asymptotic and numeric methods in cases of quasiperiodic structures with large number of "periods". Coupling coefficients are obtained for complex amplitude of resonance harmonic. Nonreciprocal Bragg phenomena are analyzed.
