A study on measurement method of shielding effectiveness using loop antenna in low-frequency

This paper describes a measurement method of electromagnetic shielding effectiveness in low frequency. In order to measure the magnetic shielding effectiveness, loop antennas are usually used. When a type of shielding material is sheet or cloth, it is easily put up inside a loop antenna. Therefore, we propose a method to measure a magnetic shielding effectiveness of materials whose type is sheet or cloth.
