Research On3D MIE Resonance All Dielectric LHM

With the development of communication, RF and microwave communicationstechnology have attracted people’s attention, especially the application of new mediain communications-related fields. Left-handed material (LHM) used onElectromagnetic field, with its electromagnetic scattering property that negativerefraction, backward-wave spread and both negative permittivity and permeabilitycharacteristics, it has a very big potential in the electromagnetic field of applications.However, the traditional metal resonator LHM doesn’t apply for terahertz band, andhas no isotropy in three-dimensional direction. So this paper presents athree-dimensional Mie-based dielectric resonator. First, the background anddevelopment of three-dimensional left-handed all-dielectric medium in the world areintroducted. And then the distribution of electromagnetic on the basic unit ofdielectric cylinder and sphere is researched based on Mie scattering theory. Thirdthe paper focuses on the current technology we can rely on, including the BSTtechnology and3D printing technology. The article builds a lot of dielectricthree-dimensional modeles, including modeling spatial configuration of the cylinderand the traditional sphere, and on this basis to improve, presented four improvedthree-dimensional left-handed medium comprising: hexagonal pyramid structure,chamfering cone structure, pore structure and po re-type ball-type cubic structure,through extensive simulation shows the spatial structure of the electromagneticcharacteristics of the individual and equivalent constitutive parameters,experimental results, most of the research model with a wide The ba nd featuresdouble negative, up67%compared to traditional media column D LHM doublenegative bandwidth up to40%. Meanwhile, the article explores the application ofthe studied structure of the antenna and the absorber, in the antenna test successfullyincreased antenna gain3.1dB, and studied the left dielectric lens antennaperformance to the antenna distance relationship, and in absorbing body Simulationof the last to get multi-frequency absorber.
