Abstract: A novel synthetic uniform circular array (SUCA) method for generating vortex electromagnetic (EM) wave carrying high orbital angular momentum (OAM) mode has the following steps. N antenna elements are placed radially to form a uniform circular array (UCA), where N is a positive integer. By rotating the array elements to various spatial locations, modifying their feeding phases, and superimposing the generated fields at various spatial locations, SUCA can beat the limit of space and configure more array elements to generate vortex electromagnetic (EM) waves carrying high mode OAMs. Meanwhile, due to the more synthetic array elements and smaller aperture than the traditional UCA, the purity of OAM mode is higher and it is more flexible to adjust the main lobe directions of these vortex waves carrying different OAM modes, and can generate vortex EM waves.

Abstract: The disclosure provides a self-biased magneto-optical non-reciprocal metasurface device. The device includes substrate layer and a sub-wavelength structure layer. The substrate layer is a material layer with a refractive index of 1 to 5 in a microwave frequency band. The sub-wavelength structure layer includes a plurality of square columnar elements arranged in a matrix period with equal period in row and column directions. The square columnar elements include magneto-optical material. The adjustment of phase and amplitude of a circularly polarized electromagnetic wave is achieved by changing the length, width and height of the square columnar elements, and thus the device attains a desired isolation and insertion loss at a center frequency f0. The parameters of the magneto-optical material are: coercivity Hc≥1000 A/m; remanence Br≥1 kGs; a voigt parameter of a permittivity tensor or permeability tensor in a working frequency band≥0.01.

Abstract: A metal wiring method for reducing gate resistance of a narrow control gate structure, wherein the gate structure is etched with first gate electrodes and second gate electrodes at regular intervals and kept with complete gate electrodes at regular intervals, thereby constituting a structure in which the first and second gate electrodes and the complete gate electrodes are spaced apart. A first contact hole is etched on the complete gate electrode to draw out metal as a first metal layer. A second contact hole is etched on a source region and a split gate to draw out metal as a second metal layer. These two metal layers are separated by a dielectric layer. A multi-point contact of the first layer of metal with the gate electrode in a Y direction reduces the gate resistance caused by an excessively long path in the Y direction of a control gate electrode.
