Rapid air interface testing method based on electrically-adjustable wave-absorbing metasurface

Abstract

The invention discloses a rapid air interface testing method based on an electrically-adjustable wave-absorbing metasurface. The method comprises the following steps: 1, deploying an electrically-adjustable wave-absorbing metasurface on one or more cavity walls of a reverberation chamber, wherein the electrically-adjustable wave-absorbing metasurface is an electromagnetic metasurface and has two working modes of total reflection and total absorption; 2, putting a reference antenna and a plurality of to-be-tested devices required by testing into the reverberation chamber, and enabling the electrically-adjustable wave-absorbing metasurface in the step 1 to work in a total reflection mode through a program to complete a reference test; 3, switching the electrically-adjustable wave-absorbing metasurface in the step 2 to work in a full absorption mode through a program, and switching back to the total reflection mode after a certain time to complete the test of the specified to-be-tested device; and 4, repeating the step 3 till that the tests of all the to-be-tested devices are completed. On the premise of not influencing the uncertainty of measurement, the total time of the air interface test can be remarkably shortened, and the air interface test of the plurality of to-be-tested devices can be quickly completed.

AI Technical Summary

Benefits of technology

This patented technology allows for quicker release from a reverberator during measurements while maintaining precise results over longer periods of time compared with traditional methods like manual adjustment or power supply interruptions. Additionally, this new technique uses a special type of material called electric conductivity absorption (ECA) which helps it efficiently transfer heat away when exposed to light waves instead of being forced into contact with another object's body. Overall, these technical improvements improve efficiency and accuracy in measuring temperature changes within different environments such as hospitals, laboratory settings, etc., especially at high temperatures where conventional techniques have trouble reaching their full potential due to insufficient cooling capabilities.

Problems solved by technology

Technologies aiming towards improving the accuracy and reliability of radiofrequency identification (RFID)-based tests involve developing efficient and reliable solutions for determining the overall radiance or specific response characteristic(SR). However, current conventional refrigerant chamber technologies require manual switching between different modes during the test procedure, leading to increased labor costs and reduced productivity compared to fully automatic control over spacecraft flight simulators.
