Abstract:
1. A waveguide, comprising: a first conductor layer and a second conductor layer that are composed of a negative dielectric constant medium having a negative real part of dielectric constant with respect to an electromagnetic wave in a waveguide mode; and a core layer that is in contact with and placed between the first conductor layer and the second conductor layer, and includes a semiconductor portion, wherein at least the first conductor layer has a depressed and projected structure, wherein, in the depressed and projected structure, a depressed portion being depressed in a thickness direction of the first conductor layer is arranged between adjacent projected portions in an in-plane direction of the first conductor layer, and wherein the depressed portion is arranged between the adjacent projected portions in the in-plane direction of the first conductor layer perpendicular to a propagation direction of the electromagnetic wave in the waveguide mode.
