Problems solved by technology

However, when this complementary dielectric electromagnetic cloak is designed, it is only calculated by coordinate transformation along a certain characteristic direction, so that the entire cloak device only shrinks or increases in size along the corresponding direction, and the electromagnetic cloaking device can only Can hide the target object in the direction of coordinate transformation of the device

Embodiment Construction

[0084]The electromagnetic cloaking device designed in the present invention requires that the limited working frequency has a wavelength similar to the size of the device itself. The electromagnetic cloaking device designed in the present invention is electromagnetic cloaking in all directions, that is, it has nothing to do with the incident direction of the incident electromagnetic wave. The material parameters of the object include dielectric constant ε and magnetic permeability μ, and the electromagnetic device designed in the present invention is composed of anisotropic metamaterials. The overall cross-section of the illusion cloaking device of the present invention is an equilateral trapezoid, and has the same material parameters along the axial direction.

[0085] Such as Figure 1 to Figure 6 As shown, the present invention provides a hallucination electromagnetic cloaking device, comprising a first core area 1, a second core area 2, a third core area 3, a complementar...

Abstract

The present invention relates to the field of electromagnetic technology, in particular to a hallucinatory electromagnetic cloaking device, the components of which include three core areas, a complementary medium area, and an hallucination area embedded in the second core area; the first core area and the third core area The regions are all triangular prisms with equal dimensions with a triangular cross-section, the second core region is a rectangular prism with a rectangular cross-section, and the complementary medium region is a quadrangular prism with an isosceles trapezoidal cross-section; the present invention is based on traditional cloaking devices On, use another hallucination device, create another hallucination cloaking device, use the hallucination device to hide the target object. By adopting the illusory cloaking device, the cloaked object is not limited to a specific direction corresponding to the cloaking device. The invention can expand the space range where the hidden object can be placed, and at the same time correspondingly reduce the size of the anti-object and the stealth device, saving cost and space.

Description

technical field [0001] The invention relates to the field of electromagnetic technology, in particular to an illusion cloaking device for electromagnetic cloaking. Background technique [0002] In 1968, the former Soviet physicist V.G. Veselago proposed for the first time that when the permittivity ε and magnetic permeability μ are both negative, the electric field, magnetic field and wave vector will form a left-handed relationship. Since this medium is not found in nature, his research results have not been experimentally verified in the last century, let alone in-depth research. In 1996, J.B.Pendry et al. designed and implemented a periodic arrangement of metal thin wires (Rod) array structure with negative equivalent dielectric constant in the microwave frequency band; in 1999, Pendry et al. proposed the use of open loop resonators (SRRs: Split Ring Resonators) to realize the medium whose equivalent permeability is negative. In 2000, according to Pendry's theoretical m...
