Description

technical field [0001] The invention belongs to the technical field of electromagnetic metamaterials and microwave electronic circuits, and in particular relates to a three-dimensional non-contact metal grid type electromagnetic supersystem, a design method and a microwave circuit. Background technique [0002] At present, electromagnetic metamaterials belong to the category of artificial electromagnetic materials. The basic principle is to use periodically arranged scatterers to regulate the transmission of electromagnetic waves, including single or comprehensive regulation of propagation direction, amplitude, phase, frequency and other dimensions. Among them, metamaterials with frequency regulation properties are called electromagnetic bandgap materials or artificial electromagnetic bandgap materials. Further, if the electromagnetic shielding material has non-contact properties, the material is a non-contact electromagnetic bandgap material. At present, non-contact electr...
