摘要：
Pulses of rf radiation with power in the megawatt range was extracted from electromagnetic surface waves. These nonradiating waves propagated on a long and thin metallic strip with most of the wave energy confined to a distance of less than a half wavelength around the strip. The electromagnetic energy of the surface waves was first extracted into rectangular waveguides in a TE01 mode and then radiated into the atmosphere with an overall efficiency of 90%.
