Abstract

The embodiment of the specification provides a terahertz wave absorber with ultra wide band and high absorption. The pattern is composed of wide cross metal gold, an IT0 film, a SiO2 layer and middle hollow cross metal gold in sequence from top to bottom. By adjusting the size of each layer model, the broadband absorption with the bandwidth of more than 400nm and the absorptivity of more than 90% can be achieved within the wavelength range of 1530nm-1950nm. And the antenna has many functions in various fields of electromagnetic waves.

Description

technical field [0001] The present application relates to the technical field of electromagnetic waves and artificial electromagnetic materials, in particular to a broadband terahertz absorber. Background technique [0002] In recent years, terahertz has been widely used in materials, chemistry, medicine, radar and many other fields. The development of terahertz radiation sources and detectors has greatly promoted the research on the theory and application of terahertz radiation. Traditional terahertz absorbing materials have low absorption rate, narrow absorption frequency band, and large size. With the development of electromagnetic wave technology, further research on electromagnetic compatibility and electromagnetic compatibility has deepened, and great breakthroughs have been made in the field of wave-absorbing materials. The broadband absorbing material is based on the electromagnetic design of the absorbing material, selects a suitable dielectric layer according to ...
