Background technology
Terahertz Technology is a kind of new technology that twentieth century grows up the end of the eighties.Terahertz frequency domain refers to that frequency is at 0.1THz ~ 10THz, cover molecular vibration and the rotation spectrum of most macromolecular substances, therefore most macromolecular substances all has obvious dactylogram characteristic at its absorption spectra of Terahertz frequency range, reflectance spectrum or emission spectra, and this point is not available for microwave.In addition, THz wave can penetrate most material to some extent, and this feature is not available for infrared radiation.These features determine the value that Terahertz Technology exists, growing THz wave technology all has great scientific value and wide application prospect in astronomy, biomedicine, safety and environmental monitoring, imaging, broadband wireless communications and radar etc., wherein the THz wave communication technology has the characteristic of millimetre-wave attenuator and optical communication, can be applied to the aspects such as indoor local area network communication.Research institution in the world about THz wave emerges in multitude, and achieves a lot of achievement in research, and Terahertz Technology will be the focus of extensively research in following a very long time world wide.
Recent domestic launches gradually for the research of THz wave function element, that Present Domestic is studied outward and the THz wave filter construction proposed is mainly based on the structure such as photonic crystal, surface plasma, these structures are often very complicated, and it is difficult in actual fabrication process, cost is higher, requires also high to processing technology and processing environment.So little, lightweight in the urgent need to proposition size, to be convenient to processing and fabricating THz wave filter is to support the development of THz wave application.
Summary of the invention
The utility model provides a kind of periodically six leaves fan-shaped engraved structure THz wave filter, and technical scheme is as follows:
Periodically six leaves fan-shaped engraved structure THz wave filter comprises signal input part, the fan-shaped engraved structure transport layer of six leaves, matrix, signal output part; The fan-shaped engraved structure transport layer of six leaves is connected with matrix, six leaves fan-shaped engraved structure transport layer comprises 50 × 50 fan-shaped engraved structure periodic units of six leaves, the fan-shaped engraved structure periodic unit of six leaves comprises six isosceles triangle engraved structures, a circular engraved structure; Signal inputs from signal input part, and arriving signal output after the fan-shaped engraved structure transport layer of six leaves, matrix, realizes carrying out filtering to signal successively.
The thickness of the described fan-shaped engraved structure transport layer of six leaves is 1 ~ 2 μm.The thickness of described matrix is 500 ~ 520 μm.Described two adjacent six leaves fan-shaped engraved structure periodic unit spacing are 10 ~ 15 μm.The base of described isosceles triangle engraved structure is 13 ~ 15 μm, and waist limit is 25 ~ 30 μm.The diameter of described circular engraved structure is 2 ~ 5 μm.The material of described matrix is High Resistivity Si material, and the material of the fan-shaped engraved structure transport layer of six leaves is copper.
The utility model have fast response time, selectivity high, be with roomy, size is little, volume is little, lightweight, save material, be convenient to make and be easy to the advantage such as integrated.
