Title:
METAMATERIAL-BASED BAND-PASS FILTER UNIT AND BAND-PASS FILTER
Document Type and Number:
WIPO Patent Application WO/2019/153449
Kind Code:
A1
Abstract:
The present invention relates to a metamaterial-based band-pass filter unit. The metamaterial-based band-pass filter unit comprises a first resonator, a first dielectric layer and a second resonator. The first resonator, the first dielectric layer and the second resonator are stacked in sequence. The first resonator is provided with a first rectangular nick in the thickness direction, wherein the first rectangular nick does not exceed an edge position of the first resonator, so as to enable one face where the first dielectric layer abuts the first resonator to be exposed from the first rectangular nick. The second resonator is provided with a second rectangular nick in the thickness direction, wherein the second rectangular nick does not exceed an edge position of the second resonator, so as to enable one face where the first dielectric layer abuts the second resonator to be exposed from the second rectangular nick. The first resonator and the second resonator are completely the same structurally. The band-pass filter unit and the band-pass filter can allow electromagnetic waves in an infrared frequency band range to pass through, while electromagnetic waves outside the infrared frequency band range are all attenuated or reflected. Moreover, the bandwidth of the passable infrared frequency band can reach 195THz, such that wide broadband needed by high-speed communication in the future can be met.
