It is shown that under certain conditions surface waves are excited on the screen. The dependence of the efficiency of excitation of surface waves on the distanced d of the line source from the ground screen is examined. Also, the asymptotic series for the radiation field is derived, and its leading term is shown to vanish for a particular value of d. Under these conditions a strong surface-wave field is maintained near the guiding surface.","PeriodicalId":242402,"journal":{"name":"IRE Transactions on Microwave Theory and Techniques","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122330092","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}

Graphs of even- and odd-mode fringing capacitances are given. These graphs can be used with simple formulas, which also are given, to determine the dimensions of the configuration that will give specified even- and odd-mode characteristic impedances or shunt capacitances. The usefulness of the graphs and formulas was demonstrated by using them to design 3-db backward-couplers. The performance of the couplers in this new configuration was typical of similar couplers made in more conventional configurations, as expected. However, the devices shown have an advantage in that they can be manufactured by relatively inexpensive and rapid printed-circuit methods and, since the region between the conductors is solid dielectric, they are unusually rugged.","PeriodicalId":242402,"journal":{"name":"IRE Transactions on Microwave Theory and Techniques","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126211671","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}

The methods applicable in this region differ sufficiently from those at lower frequency to constitute a rather well-defined discipline. This area is the subject of our review. Several subjects contiguous to the microwave domain are excluded. Thus, antenna and propagation problems do not exhibit so clearcut a change with wavelength, and are mentioned only indirectly. The electronic aspects of microwave generators are also omitted, although much work on the circuits for these generators is necessarily included.","PeriodicalId":242402,"journal":{"name":"IRE Transactions on Microwave Theory and Techniques","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1955-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116812998","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}
