Abstract: Provided is a testing apparatus for an active current control-type non-contact superconductive exciter having a hybrid magnet installed therein, and a high-temperature superconductive rotating machine using same. Provided is principally characterized by having a hybrid magnet, in a module form, in which a permanent magnet, a DC electromagnet and an AC electromagnet are used together, wherein the hybrid magnet is set in a plurality along the circumferential direction of a ring-shaped iron stator, is formed to correspond to the outer side of a rotor, having a high-temperature superconductive tape (or a second-generation high-temperature superconductive wire), of a non-contact superconductive exciter, and thus enables a selected operation (charging, discharging and the like) before and after rotation of a driving motor.

Abstract: In an aspect, described herein is a dynamically controllable optoelectronic smart window which utilizes a diffraction grating for selective transmission or rejection of a specific region of the electromagnetic spectrum, for example the infrared, near-infrared and/or visible regions. Window embodiments described herein may further utilize a selectively controlled and/or patterned total internal reflection layer to assist with the selective rejection of a specific spectral region while allowing for transmission of another specific spectral region. In another aspect, the present invention provides methods for dynamically controlling the transmission or rejection of solar near-infrared and/or visible radiation.
