  • Harmonic oscillator and preparation method thereof, filtering device and electromagnetic wave device
    Patent number: 9799941
    Abstract: The disclosure relates to a harmonic oscillator and a preparation method thereof, a filtering device and an electromagnetic wave device. The harmonic oscillator includes at least one dielectric slab and response units attached on one surface of the at least one dielectric slab, where the response units are structures manufactured by conductive material and provided with geometric patterns. According to the technical solution of the disclosure, the filtering device and the electromagnetic wave device with the harmonic oscillator are good in structure stability. Swinging of a harmonic oscillator sheet layer is low in loss. The Q value of the harmonic oscillator prepared by the disclosure is high; and loss of a resonant cavity, the filtering device and a microwave device with the harmonic oscillator is obviously reduced.
