Document Type and Number:
WIPO Patent Application WO/2023/123853
Kind Code:
A1
Abstract:
Provided in the present invention is an on-chip quadrilateral resonator based on spoof surface plasmon polaritons. The quadrilateral coupled resonator is designed and produced using an on-chip process, and is composed of an inner ring resonator and an outer ring resonator. Metal gratings of the outer ring resonator are connected to a quadrilateral metal outer ring and extend inwards a certain distance; metal gratings of the inner ring resonator are connected to a quadrilateral metal inner ring and extend outwards a certain distance; the extension lengths of the metal gratings connected to the outer ring gradually reduce from the middle to two sides; and the on-chip quadrilateral resonator is excited by the coupling of microstrip lines and impedance matching branches. A frequency point, the intensity and a Q value of each resonant mode can be adjusted by means of adjusting structural parameters of the resonator, and the position and quantity in a chip structure. The resonator has a simple structure, large resonant intensity, high quality factor and strong field binding, and conforms to design rules of various chip processes such as CMOS, gallium arsenide and indium phosphide; and by means of equal-proportion scaling, high-Q-value resonators of a microwave band, a millimeter wave band and a terahertz wave band can be realized.
