The array efficiently couples blackbody radiation from 200 GHz to 600 GHz to Schottky Barrier Diodes (SBDs) in a differential topology. An antenna-detector co-design results in an average Noise Equivalent Power (NEP) of 0.9 pW/$sqrt{text{Hz}}$. An extremely small array periodicity is achieved by using two orthogonal polarizations. Such configuration enables passive imaging with a near-diffraction limited resolution while simultaneously maintaining a high optical efficiency of 42%. The array is currently in tape-out and measurements will be presented at the conference.","PeriodicalId":6686,"journal":{"name":"2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"54 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86079951","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}

As a result, it can affect the functionality of some biological tissues. Neuronal tissue is one of the most susceptible types due to its high sensitivity to environmental changes, such as electric field and temperature. Here we investigate the effect of MMW mediated heating and conventional thermal heating on action potential voltage initiation in spontaneously active interneuron of leech. The results demonstrate that MMW radiation has a different effect to thermal heating but only at initial stages of sample heating.","PeriodicalId":6686,"journal":{"name":"2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"57 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82767457","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}
