For the description of such field Lorentz — Maxwell average microscopic equations are used. Each element of the multilayered antenna is described with the help of the generalized functions concentrated on smooth surfaces. Such approach allows to present behavior of an electromagnetic field by means of one differential equation which factors are the generalized functions. The special method is developed, allowing obtaining the general solution of the differential equations of the given class. In an obvious kind the exact solution representing external electromagnetic field of MWNT antennas is obtained.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133745923","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}

However, the formed images suffer from speckle noise, especially if single-look observation mode is used. Then, filtering is often applied to improve image quality and provide better estimation of radar cross-section and other parameters of sensed scenes. Recently, a novel class of image filters has proved to be very successful in the removal of additive white Gaussian noise from natural images; these filters are based on nonlocal image modeling, i.e. they exploit the mutual self-similarity of image patches at different locations in the image. These filters have been shown in several benchmarks to significantly outperform all previous techniques. In this paper, we evaluate the performance of nonlocal filters applied to the denoising of single-look SAR images corrupted by speckle with a Rayleigh distribution, taking advantage of exact forward and inverse variance-stabilizing transformations. Numerical simulations demonstrate the success of this approach against several known despeckling methods.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"378 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125709419","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}
