The structure of an artificial magnetic conductor (AMC) of alternating dielectric layers with high and low permittivity is presented. By numerically calculating the frequency dependence of the reflection coefficient on the AMC with a finite number of ceramic layers separated by air gaps, it is shown that with a decrease in the number of layers from 5 to 1 and while maintaining the total thickness, the frequency band of the AMC narrows from 14 to 11%. The effectiveness of the application of the AMC structure as a small-sized shield of electromagnetic radiation with a dipole emitter located on its surface is shown.

基于具有各向异性介电常数的复合材料的人造磁导体及其作为小屏的应用

介绍了具有高和低介电常数的交替介电层的人造磁导体 (AMC) 的结构。通过数值计算反射系数对 AMC 的频率依赖性，其中有限数量的陶瓷层由气隙隔开，结果表明，随着层数从 5 层减少到 1 层，在保持总厚度的同时，频率AMC 的频带从 14% 缩小到 11%。显示了应用 AMC 结构作为具有位于其表面上的偶极发射器的小型电磁辐射屏蔽的有效性。
