In contrast to the approach used in the other papers [1]-[3] the general form of the electromagnetic equation of the gyrotropic waves has been considered. The dispersion equation analysis shows that attenuation of one of the mode tends to zero in the perpendicular to the magnetic field direction while along this direction the attenuation is finite (Fig. 1). Basing on this feature we can suppose that low frequency electromagnetic fluctuations tend to expand along the magnetic field. It forms in the ionosphere long areas with invariable direction of the electric field and current and weakly variable magnitude of these parameters. To check this conclusion the direct problem of the evolution of an electromagnetic fluctuation has been solved numerically. The results show that spherically symmetric fluctuation expands along the magnetic field lines by 5–30 times while in some cases the widening is fully absent (Fig. 2).","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"27 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":"128480276","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 phenomenon takes place at any frequency range — not only at the optical regime —, and it has been explained in terms of the excitation of surface waves along the periodically structured metal screens used in the experiments. EOT also takes place, however, through slit gratings for a polarization precluding the excitation of such surface waves. It can be also observed through electrically small diaphragms located inside hollow pipe waveguides. Along the last three years, some of the authors have developed models explaining the phenomenon in terms of simple concepts extracted from conventional waveguide theory. The models lead themselves to simple circuit equivalents which help the understanding of the underlying physics. This paper summarizes the main results obtained by the members of the group and some other collaborators concerning the capabilities of the proposed approach.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"34 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":"129278651","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}
