Abstract: Topological insulators can be utilized in a new type of infrared photodetector that is intrinsically sensitive to the polarization of incident light and static magnetic fields. The detector isolates single topological insulator surfaces and allows light collection and exposure to static magnetic fields. The wavelength range of interest is between 750 nm and about 100 microns. This detector eliminates the need for external polarization selective optics. Polarization sensitive infrared photodetectors are useful for optoelectronics applications, such as light detection in environments with low visibility in the visible wavelength regime.

Abstract: A novel thermal source comprising a semiconductor hyperbolic metamaterial provides control of the emission spectrum and the angular emission pattern. These properties arise because of epsilon-near-zero conditions in the semiconductor hyperbolic metamaterial. In particular, the thermal emission is dominated by the epsilon-near-zero effect in the doped quantum wells composing the semiconductor hyperbolic metamaterial. Furthermore, different properties are observed for s and p polarizations, following the characteristics of the strong anisotropy of hyperbolic metamaterials.

Abstract: A method for monitoring the power consumption of an electrical consumer that has a capacitive load and the controllable circuit element and the consumer are connected in series. The amplitude of the current flowing through the consumer, the voltage dropping across the consumer, and the change over time of the voltage dropping across the consumer are sensed. An allowed operating current amplitude is calculated from the voltage dropping across the consumer and from a predefined power. A charging current amplitude of the capacitive load is calculated from the change over time of the voltage dropping across the consumer. An allowed instantaneous current amplitude is calculated. The allowed instantaneous current amplitude is compared with the amplitude of the current flowing through the consumer and the electrical resistance of the circuit element is increased if the amplitude of the current flowing through the consumer is greater than the allowed instantaneous current amplitude.

Abstract: The present disclosure pertains to systems and methods for using time synchronized measurements of a generator output and an electrical bus, together with generator control algorithms to synchronize the frequency, voltage, and phase of a generator, or group of generators, prior to electrically connecting the generator to the electrical bus. More particularly, but not exclusively, the present disclosure pertains to systems that may be operated in an islanded configuration and in which one or more generators may be selectively synchronized based on a common time reference. The common time reference may allow the generators to be synchronized by autonomously driving one or more generators to a specified phase angle and frequency.
