T he designs theoretical dat a and calibration procedure and the results o fthis kind o fprobe are given . It is char- acterized by it s capability o fcarrying much higher power o fmicrow ave, good airtightness , sim ple structure and easy op- erat ion. It is an e ective and practical w ay t o measure t he peak pow er o fHPM .
