Coherent radiation of relativistic electrons in metamaterials based on the SRR/wire-grid unit cell in millimeter wavelength range

FLAP Collaboration: Tasks and Perspectives. Study of Fundamentals and New Applications of Controllable Generation of Electromagnetic Radiation by Relativistic Electrons Using Functional Materials

“…The modern status of research in this field worldwide is characterized by fragmentary studies along several directions included in the project. In particular, first observation of generation of reverse Vavilov-Cherenkov radiation by relativistic electrons interacting with metamaterials was reported [3]. Note that reverse refraction was predicted long ago and was observed with photon beams.…”
