Abstract

Resonance backscattering at the fundamental magnetic mode and the wave properties of linear structures consisting of subwave dielectric elements in the form of planar thin rings excited by the displacement currents of an incident microwave-range plane electromagnetic wave have been investigated. It is shown that the magnetic field at the main resonance frequency for a single ring is concentrated inside the ring and in the near-field zone, whereas for structures consisting of two or more rings the magnetic field is also registered in the far-field zone. The main magnetic resonances measured in the spectrum of electromagnetic fields for one and two planar rings coincide with the calculated resonance frequencies.

环形介质线性结构对GHz平面电磁波的共振散射

摘要

已经研究了在基本磁模式下的共振反向散射以及由入射微波范围平面电磁波的位移电流激发的平面薄环形式的子波介电元件构成的线性结构的波特性。结果表明，单个环的主共振频率处的磁场集中在环内部和近场区域，而对于由两个或多个环组成的结构，磁场也记录在远场区域。在一个和两个平面环的电磁场频谱中测得的主要磁共振与计算出的共振频率一致。
