Device and method for measuring partial shielding effectiveness of curved surface of electromagnetic shielding clothing

Abstract

The invention provides a device and method for measuring the shielding efficacy of a local curved surface of electromagnetic shielding clothes, and solves the problem that the electromagnetic wave shielding effect of the local area of the curved surface of electromagnetic shielding clothes cannot be mastered. The device comprises a curved-surface casing, a curved-surface cloth supporting mechanism, pressure tablets and a signal reception system, the upper, lower and side portions of the curved-surface casing are provided with pressure tablet areas respectively, the side portion of the curved-surface casing is provided with the curved-surface cloth supporting mechanism, and the back side of the curved-surface cloth supporting mechanism is provided with the slidable signal reception system;and the pressure tablets match the pressure tablet areas, the clothes cloth is fixed to the side portion of the curved-surface casing via the pressure tablets, and the clothes cloth is supported by the curved-surface cloth supporting mechanism. According to the device and method, manufacturing is simple, operation is convenient, design is reasonable, test is accurate, the cost is low, the shielding efficacy of the local curved-surface area of the electromagnetic shielding clothes can be measured scientifically and accurately, and related data can be obtained accurately and serves as basis forsubsequent processes.

Description
