Susceptibility testing using GTEM cell

The GTEM cell has been found as a suitable test environment for radiated susceptibility testing of electronic equipment. In Microwave Measurement Laboratory, Department of E & ECE, IIT Kharagpur, a GTEM cell with test volume 1 m /sup 3/ and characteristic impedance of 50 /spl Omega/ has been fabricated and is being successfully used for radiated emission and susceptibility testing. For susceptibility testing the device is intentionally put in the required amount of electric field. In this paper a method of moment based procedure is described to evaluate the field produced inside the cell due to a certain amount of applied power. The theoretical value is in good agreement with the measured one.
