  • Patent number: 8879138
    Abstract: A surface plasmon polariton modulator capable of locally varying a physical property of a dielectric material to control a surface plasmon polariton. The surface plasmon polariton modulator includes a dielectric layer, including first and second dielectric portions, which is interposed between two metal layers. The second dielectric portion has a refractive index which varies with an electric field, a magnetic field, heat, a sound wave, or a chemical and/or biological operation applied thereto. The surface plasmon polariton modulator is configured to control one of an advancing direction, an intensity, a phase, or the like of a surface plasmon using an electric signal. The surface plasmon polariton modulator can operate as a surface plasmon polariton multiplexer or a surface plasmon polariton demultiplexer.

    Abstract: A method of controlling a heat pump system of an electric vehicle, whereby power consumed for air conditioning is reduced during driving in a low load state in a heating mode, includes determining whether a heat dissipation amount insufficient condition of an indoor condenser is satisfied in the heat pump system of the electric vehicle. When it is determined that the heat dissipation amount insufficient condition of the indoor condenser is satisfied, measuring current revolutions per minute (rpm) of a compressor. It is determined whether the measured rpm of the compressor is greater than a minimum rpm limit of the compressor. When it is determined that the measured rpm of the compressor is greater than the minimum rpm limit of the compressor, the rpm of the compressor is reduced.
