Abstract

The new phenomenon related with enhanced microwave transmission and beaming through a subwavelength slot placed into a corrugated conducting plate has been experimentally observed, in the microwave range, compared with the case of the single isolated slot. It is very similar to that happening for optical wavelengths where the surface plasmons model is employed to describe the metal. The phenomenon is also present in the microwave range where the perfect conductor model applies. Future applications in antennas can be possible.
