摘要： The present disclosure relates to an electromagnetically transparent metamaterial, which comprises a substrate and a plurality of man-made metal microstructures arranged periodically inside the substrate. When an electromagnetic wave propagates through the metamaterial, each of the man-made metal microstructures is equivalent to two identical two-dimensional (2D) circuits, which are placed respectively in a direction perpendicular to an incident direction of the electromagnetic wave and in a direction parallel to the incident direction of the electromagnetic wave, and each of which comprises an inductor branch and two identical capacitor branches that are symmetrically connected in parallel with the inductor branch. The 2D circuits are associated with a waveband of the electromagnetic wave so that both a dielectric constant and a magnetic permeability of the metamaterial are substantially 1 when the electromagnetic wave propagates through the metamaterial. By adopting the wave-transparent principle different from that of the conventional electromagnetically transparent material in the present disclosure, the electromagnetic wave transparent property is not limited by the material of the substrate, so the application scope of the electromagnetically transparent material is greatly enlarged.

摘要： A planar immersion lens can include any number of features. A planar immersion lens can be configured to control a phase profile of an incident wave by modulating the incident wave with sub-wavelength structures of varying impedances. The planar immersion lens can also be directly excited, with electronics or other subwavelength sources coupled to the planar immersion lens, to generate a wave with the desired phase profile. The planar immersion lens can include a plurality of metallic elements and passive elements disposed over a substrate. The passive elements can be selected, based on both the intrinsic and mutual impedances of the elements, to shape the spatial phase profile of the incident wave within this phase range. The phase gradient can be introduced along the incident material/refractive material interface to focus the incident wave into the refractive material having wave components at or beyond the critical angle. Methods are also provided.

摘要： The invention provides a detector (10) comprising a metamaterial absorber (14, 16, 18) and a micro-bolometer (22) arranged to detect terahertz (THz) radiation. The metamaterial absorber can absorb multiple frequency bands, from the infrared and the THz regions of the electromagnetic spectrum. The detector is scalable to be suitable for use in a focal plane array. The invention also provides a hybrid of a plasmonic filter, e.g. for optical radiation, and a metamaterial absorber for terahertz (and/or infrared) radiation, to create a single material capable of absorbing narrow band terahertz radiation and filtering radiation in another part of the spectrum, e.g. optical radiation. Such material has great potential in future imaging technology where hybridisation can maximise the spectral information density of an optical system.
