A simple theoretical model for predicting resonant frequencies of modes of the WGMDR for microwave and millimeter wave integrated circuits is presented. The un-symmetric field distribution for WGE mode in the axial direction is taken into account. Highly useful modeled results such as the effect of DR, aspect ratio, substrate width, and their dielectric constants on each mode are discussed. The effect of the spacer on frequency of MIC WGMDR is also discussed.","PeriodicalId":23431,"journal":{"name":"Twenty Seventh International Conference on Infrared and Millimeter Waves","volume":"19 1","pages":"279-280"},"PeriodicalIF":0.0,"publicationDate":"2002-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79359805","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}

This research supports an international effort to design the next generation of linear electron-positron colliders with anticipated center of mass energies of 0.5 TeV and beyond. In particular, this program supports development of a W-band accelerator now underway at the Stanford Linear Accelerator Center. CCR is developing a 91.392 GHz gyroklystron to produce 10 MW of RF power with efficiency greater than 40% and a gain of 55 dB. Achievement of 10 MW of peak power would advance the state of the art for W-Band amplifiers by two orders of magnitude and potentially lead to other applications, including land- and ship-based radar, medical accelerators, and materials processing.
