Airy beam-like directional THz beams are obtained from GGSs designed to give appropriate phase delay in each scattered radiation from each grooves. Our findings may open the way for a development of novel THz radiation source based on the wide variety of metallic grating structures.","PeriodicalId":6653,"journal":{"name":"2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"40 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87507242","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}

To demonstrate a high-precision calorimetric measurement, the influence of heat leakage in an adiabatic waveguide (AW) of the calorimeter was investigated. Thermal responses by heat generation due to loss of the AW were independently measured using a gold foil shield. The index $rho$ that represents the ratio of heat leakage to the total generated heat in the AW was estimated by analyzing the thermal response and scattering parameters of the AW. As a result, the index $rho$ was found to be 0.50 ± 0.05 in the frequency range of 140–220 GHz.","PeriodicalId":6653,"journal":{"name":"2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz)","volume":"60 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87013541","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}
