Five Minutes with…Professor Tatsuo Itoh on Metamaterial Leaky Wave Antennas
IDGA: You are an expert in metamaterial leaky wave antennas. First, could you describe precisely what metamaterial is?
TI: Metamaterial is an artificially made structure which has electromagnetic properties not found in nature. For instance, structures with simultaneously negative permeability and negative dielectric constant can be synthesized. In such a structure the phase of the wave propagates along the opposite direction of the energy transfer, thereby backward wave can be obtained....
