Abstract

The invention discloses an all-metal metamaterial lens based on a near-field convergence function and a phase shift design method thereof. The all-metal metamaterial lens is composed of a plurality of array units, and the array units with different phase shifters are arranged on an XOY plane according to a pre-designed phase shift distribution rule. Each unit comprises four metal layers 1 and three air layers 2, the four metal layers 1 and the three air layers 2 are arranged at intervals; each metal layer 1 comprises a square spiral gap; and the metal layer 1 of each unit is formed by rotating one square spiral gap by 0 degree, 90 degrees, 180 degrees and 270 degrees to obtain a center rotational symmetry structure. With the all-metal metamaterial lens based on the near-field convergence function and the phasor shift design method thereof of the invention adopted, the problems of high temperature resistance and mechanical stability of the all-metal metamaterial lens are solved.

Description

technical field [0001] The invention belongs to the technical field of microwave device engineering, and in particular relates to an all-metal metamaterial lens based on a near-field convergence function and a phase shifting design method thereof. Background technique [0002] Microwave lenses are of great value in a variety of scenarios, including medical and satellite communications. In terms of medical treatment, the focusing lens can focus the electromagnetic beam, which has the characteristics of good directionality, high thermal efficiency, and high gain in the microwave hyperthermia of tumors; in terms of satellite communication, the microwave lens can receive multiple satellite signals, which greatly improves the performance of the antenna . However, traditional lenses have problems such as large volume and high cost. Therefore, metamaterial lenses with low profile, compact structure and low cost have been widely used. [0003] Existing metamaterial lenses are gene...
