Abstract

A method for generating high power electromagnetic radiation based on double-negative metamaterial (DNM), includes providing electrons of an electron beam moving in a vacuum close to an interface between the DNM and the vacuum at a predetermined average speed larger than a phase velocity of an electromagnetic wave propagating in the DNM so as to generate coherent high power radiation. The method can be applied but not limited to high power and compact Terahertz radiation sources and Cherenkov particle detectors and emitters.
