A multifunctional spatial beam compiler based on plasmonic metamaterials

Abstract

The invention relates to a multifunctional wave beam compiler based on a plasma meta-material, and the structure comprises a reflecting plate, a dielectric substrate disposed above the reflecting plate, and a solid plasma resonant unit on the dielectric substrate, wherein the solid plasma resonant unit is provided with a lumped resistor. A solid plasma is implemented through an array formed by PINunits, and the PIN units are isolated by an isolating layer. The excitation is controlled through programmable logic arrays loaded at two ends of the PIN units. The compiler achieves the good absorption of TE waves and TM waves. The compiler can achieve the excitation of different resonant units when an excitation area of the resonant unit formed by the solid plasma is controlled in a programmable mode. The compiler also can achieve the UWB (ultra wide band) absorption of electromagnetic waves, and achieves the compiling of a spatial beam. The compiler also can achieve the absorption of the electromagnetic waves at lower frequencies in a smaller physical dimension, and achieves the compiling of the spatial beam through the excitation of different plasma areas.

Description

technical field [0001] The invention relates to a multifunctional space beam compiler based on plasma metamaterials, belonging to the technical fields of radio communication and microwave devices. Background technique [0002] In recent years, with the continuous deepening of research on metamaterials, certain results have been achieved in the field of practical applications. Compared with classic absorbing materials, new absorbing materials have been widely used in civil and military applications. In terms of civil affairs, there are the effects of electromagnetic radiation on the human body, the interference of electromagnetic waves on aircraft, and the electromagnetic leakage of electronic instruments. These hazards have attracted people's attention. In the military, stealth technology has always been the focus of research. The stealth of naval and army equipment not only prevents it from being detected, but also improves the efficiency of military operations. Metamateria...

AI Technical Summary

Problems solved by technology

In general, metamaterials in the traditional sense are difficult to obtain a tunable absorption spectrum with a certain absorption bandwidth, and general metamaterials can be used in military stealth radars, etc., but they cannot encode the electromagnetic waves emitted and absorbed, so that The purpose of effectively transmitting data cannot be achieved
