Towards EM based logic implementation using periodically corrugated metamaterial structures

In this paper, we have explored the feasibility of performing complex logic operations using periodically corrugated metamaterial waveguides. Selective manipulation of the free carrier concentration of the GaAs dielectric via external stimuli alters the filtering characteristics of the waveguide structure, enabling control over the propagation of terahertz carrier signal. We demonstrate that integration of individual control elements together can be utilized to implement AND and OR logic structures.
