Title:
METAMATERIAL, RADOME AND AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2021/022885
Kind Code:
A1
Abstract:
The present invention provides a metamaterial, comprising a base material layer and a metal microstructure layer superposed on the base material layer. The metal microstructure layer has periodically arranged single-direction communication structures. The base material layer and the metal microstructure layer together form an integral whole, and the end of the integral whole in a single direction is connected to a connection terminal, and communicates with an external power supply by means of the connection terminal to form a conductive path for electrical heating based on the ohmic heating characteristics of metal. In addition, the present invention further provides a radome and an aircraft. According to the technical solution provided by the present invention, specific structural design is performed on the metal microstructure layer, so that the metal microstructure layer not only serves as an electric heating unit having an electric heating de-icing function, and but also serves as an electromagnetic modulation structure that allows electromagnetic signal transmission within the working frequency range of an electromagnetic transceiver device, but shields the electromagnetic waves outside the working frequency range so as to suppress the interference of clutter signals.
