摘要： Embodiments of the present disclosure relate to an impedance matching component and a hybrid wave-absorbing material. The impedance matching component is disposed between a first medium and a second medium, and comprises a plurality of functional sheet layers. Impedances of the functional sheet layers vary continuously in a stacking direction of the functional sheet layers, with the impedance of a first one of the functional sheet layers being identical to that of the first medium and the impedance of a last one of the functional sheet layers being identical to that of the second medium. According to the impedance matching component and the hybrid wave-absorbing material of the present disclosure, the impedance matching component has a graded impedance, with an impedance value thereof at a side being identical to that of a first medium and an impedance value thereof at the other side being identical to that of a second medium. The continuous changes in the intermediate portion eliminate sudden transitions of the impedance between the first medium and the second medium. Thereby, the problems of partial reflection and energy loss of electromagnetic waves when propagating through an interface between different media are overcome. Furthermore, the hybrid wave-absorbing material of the present disclosure has improved wave-absorbing performances.

摘要： The present invention relates to an antenna based on a metamaterial and a method for generating an operating wavelength of a metamaterial panel. The antenna comprises a radiation source, and a metamaterial panel capable of converging an electromagnetic wave and operating at a first wavelength. The metamaterial panel is adapted to convert the electromagnetic wave radiated from the radiation source into a plane wave and to enable the antenna to simultaneously operate at a second wavelength and a third wavelength which are smaller than the first wavelength and are different multiples of the first wavelength. The present invention further provides a method for generating an operating wavelength of a metamaterial panel for use in the aforesaid antenna, which comprises: acquiring a numerical value m 3 /m 2 that is within a preset error range relative to a ratio » 3 /» 2 of a third wavelength » 3 to a second wavelength » 2 ; calculating a lowest common multiple m 1 of m 2 and m 3 ; and generating the operating wavelength » 1 of the metamaterial panel, which is represented as » 1 =» 2 (m 1 /m 2 ) or » 1 =» 3 (m 1 /m 3 ). By designing the operating wavelength of the metamaterial panel, the antenna is able to operate at different wavelengths simultaneously; and the electromagnetic wave from the radiation source can be converted into a plane wave. These improve the convergence performance and reduce the volume and size of the antenna.

摘要： The present invention relates to a metamaterial antenna, where the metamaterial antenna includes an enclosure, a feed, a first metamaterial that clings to an aperture edge of the feed, a second metamaterial that is separated by a preset distance from the first metamaterial and is set oppositely, and a third metamaterial that clings to an edge of the second metamaterial, where the enclosure, the feed, the first metamaterial, the second metamaterial, and the third metamaterial make up a closed cavity; and a central axis of the feed penetrates center points of the first metamaterial and the second metamaterial; and a reflection layer for reflecting an electromagnetic wave is set on surfaces of the first metamaterial and the second metamaterial, where the surfaces are located outside the cavity. The present invention uses distinctive electromagnetic properties of the metamaterial, and performs reflections of the electromagnetic wave for multiple times to improve aperture efficiency of the antenna and accomplish good far-field radiation field responses. In addition, the design of reflecting the electromagnetic wave for multiple times reduces thickness of the antenna significantly and makes an antenna system smaller.

摘要： A front feed microwave antenna, which comprises a radiation source, a first metamaterial panel used for radiating an electromagnetic wave emitted by the radiation source, a second metamaterial panel, and a reflective panel affixed to the back of the first metamaterial panel. The electromagnetic wave is emitted via the first metamaterial panel, refracted by entering the second metamaterial panel, reflected by the reflective panel, and finally re-refracted by reentering the second metamaterial panel, then finally parallel-emitted. Employment of the principle of metamaterial for manufacturing the antenna allows the antenna to break away from restrictions of conventional concave lens shape, convex lens shape, and parabolic shape, thereby allowing the shape of the antenna to be panel-shaped or any shape as desired, while allowing for reduced thickness, reduced size, facilitated processing and manufacturing, reduced costs, and improved gain effect.
