Electromagnetic surface wave propagation on a corrugated metal plate is confirmed by a cold test in the X‐band. The measured cut‐off frequency is almost in agreement with the theoretical cut‐off frequency. The propagation is damped at a frequency region higher than the cut‐off frequency. The periodicity of the propagation power to the frequency is confirmed. For the confirmation of these characteristics, it is necessary that the corrugated metal plate is enclosed within a microwave absorber. © 2013 Institute of Electrical Engineers of Japan.
