At room temperature, the metasurface can achieve broadband absorption, the absorptivity exceeds 90% between 0.50 THz and 1.95 THz with the relative bandwidth of 118%; when the temperature rises to 340 K, it serves as a coding rnetasurface, single-beam and dual-beam steering with different diffraction angles can be realized by designing different coding sequences.

Simulation results show that low insertion loss and high channel isolation are achieved by using the structure of serial-parallel loaded spiral inductor.

The metasurface unit cell is folded to form an origami structure, which is a straightforward way to change metasurface shape. The transmission electromagnetic performance of the unit cell is steady while the angle of incident waves changes from -60 to 60 degrees. In this paper, the folded angle of 45 degree is chosen. Every four cells fold in different ways to form a supercell. The total amounts of supercells are $30times 30=900$. Next, deep learning is utilized to compute the compensation phases of 3600 elements for generating hologram imaging. These phases determine the rotation angles of the unit cells. A left-handed circular polarized (LHCP) wave transmits the hologram structure and subsequently generates an image with the shape of the letter J on the imaging plane. This is validated by the simulations in the commercial electromagnetic software CST.","PeriodicalId":198168,"journal":{"name":"2022 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130150057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A terahertz imaging system based on a cold cathode gyrotron is designed in this paper. In the system, the wave of higher-order mode generated by the gyrotron is converted to a quasi-optical Gaussian beam by a mode converter, which then passes through the object and is received by a terahertz detector for analyzing and imaging.
