  • Patent number: 11916297
    Abstract: A liquid crystal antenna and a method for forming a liquid crystal antenna are provided. The liquid crystal antenna includes a first substrate; a second substrate opposite to the first substrate; and a liquid crystal layer disposed between the first substrate and the second substrate. A first conductive layer is disposed on a side of the first substrate facing toward the second substrate; a second conductive layer is disposed on a side of the second substrate facing toward the first substrate; the second conductive layer at least includes a plurality of radiation electrodes; an external metal layer is disposed on a side of the first substrate facing away from the liquid crystal layer; and the external metal layer is connected to a fixed potential.

  • Publication number: 20230400414
    Abstract: A method of performing coherent anti-stokes Raman spectroscopy (CARS) includes generating first and second optical pulse trains having different and adjustable repetition rates. One of the pulse trains is directed in a CW direction and the other in a CCW direction. A frequency shift and a first linear chirp is applied to optical pulses in the first optical pulse train. A second linear chirp is applied to optical pulses in the second optical pulse train. The first and second linear chirps having a common chirp rate. One of the chirped optical pulse trains is used as a pump beam and the other is used as a Stokes beam. The first and second chirped optical pulse trains are combined to define a combined beam. The combined beam is provided to a CARS spectroscopic system for exciting a resonant mode in a sample and generating a CARS signal.

  • Patent number: 10005973
    Abstract: A pulverized coal gasification furnace with multi-level feeding of high speed circulating gasification agent which includes a pulverized coal gasification furnace and a gasification method. The present invention solves the existing problems in short life of burner, uneven slag deposition on the surface of the gasification device which causes burning and corrosion, and uneven temperature distribution along the height direction. The steps are: 1. setting parameters for the gasification chamber; 2. feeding pulverized coal; 3. burning pulverized coal to form molten slag; 4. gasification process of molten slag inside the gasification furnace; 5. removing slag. In the present invention, the furnace body is divided into different levels for the gasification agent, the internal temperature of the furnace along the height direction is evenly distributed, and the furnace is applicable to the coal types which has severe change in ash viscosity in response to temperature changes.
