Abstract
Enhanced microwave transmission and beaming through a subwavelength slot placed into a corrugated conducting plate is experimentally observed compared with the case of the single isolated slot. This phenomenon is similar to that happening for optical wavelengths where surface plasmons model is employed to describe the metal. This letter shows that the phenomenon is also present in the microwave range where perfect conductor model applies. Enhanced subwavelength transmission and beaming stimulates new research for future applications.
