The approach is based on the analytical regularization method. Seeking the solution by its integral representation, we determine the singular features of the kernel, and decompose it into the singular canonical part, and a regular remainder. Then, utilizing an appropriate technique, the problem is equivalently reduced to integral equation of the first kind, and then - to an infinite system of linear algebraic equations of the second kind. The last is well conditioned always, and its solution can be efficiently obtained to any pre-specified accuracy.","PeriodicalId":141554,"journal":{"name":"2008 12th International Conference on Mathematical Methods in Electromagnetic Theory","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123834989","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 solution of a problem is constructed as product of functions so that boundary conditions have been satisfied. In case of zero boundary conditions one of factors in the solution tends to zero on border and consequently near the border can be accepted as small parameter. The Helmholtz equation becomes singularly perturbed and it allows constructing the solution as a boundary layer. The asymptotic expansion is obtained in an explicit form for domains which borders consist on the various combinations of curves of a special kind. It is shown, that asymptotic expansion of the solution is continuous in all a boundary layer.","PeriodicalId":141554,"journal":{"name":"2008 12th International Conference on Mathematical Methods in Electromagnetic Theory","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125122111","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}
