Discrimination of Modes of Double-and Single-Negative Grounded Slab

In this paper, we investigate theoretically the waves propagation in a lossless double-negative grounded slab (DNG). This study is performed by the Transverse Resonance Method (TRM). The proper or improper nature of real and complex modes is observed. They are highly dependent on metamaterial parameters, i.e. ɛrnegative, μr-negative, or both. Numerical… CONTINUE READING
