In this paper, we present several experimental and theoretical studies showing the feasibility of active photonic crystal controlled either by electrical elements or by light. The controllability of photonic crystals at centimeter wavelengths is prop

Terahertz technology has moved on from being a useful but expensive circuit technique, applied largely in astronomy and space science, to become a subject in its own right, with important applications - terahertz imaging in particular. Indeed, the dr

A finline-based left-handed transmission line is presented and analyzed. The transmission line is periodically loaded by single split ring resonators and thin wires in order to synthesize a negative permeability and permittivity propagation medium. T

A novel planar electron waveguide coupler is proposed as an electronic switch. The structure consists of two quantum wires interconnected by a dual branch coupling scheme which is assumed to be controlled by an electrostatic potential. Switching is p
