Desmostración experimental device for the refusal to the microwave frequency oriented teaching refraction metamaterials.

摘要

Device for experimental demonstration of a refusal to microwave frequency oriented teaching refraction metamaterials.; The invention consists of a device to experimentally demonstrate the phenomenon of negative refractive microwave. The device comprises two prisms, one positive refractive index (6) and one with negative index (5) to the microwave frequency, a dielectric support (4) to accommodate the prisms and two microwave antennas, a station (1) and receiving (3), horn type.; The prism negative index (5) consists of a series of stacked layers, each formed by two metal planes (11) including at least two layers of dielectric material (9) and at least one sheet of dielectric on the inserted which it is recorded a two-dimensional periodic lattice (10) of metal ring resonators open type.; The device is especially applicable in the teaching of metamaterials in teaching.
