Caustic influence is taken into account, and the contribution of stationary phase points of reflected field to the far-side radiation is discussed.

Tweeks are observed during nighttime and represent response of the Earth-ionosphere waveguide to excitation by lightning strokes. Tweeks are formed by series of pulses consecutively reflected from the waveguide boundaries under different incident angles depending on a source-observer distance and effective ionosphere height along a propagation path. The tweek signals demonstrate the propagation of a few Earth-ionosphere waveguide modes. We determined propagation path's parameters such as source range, ionosphere height, and azimuthal orientation of a propagation path. We used then a time-frequency representation of analyzed tweek waveforms to infer separate branches, corresponding to different waveguide modes. Obtained results show the increase of attenuation for higher modes with increase of a source distance.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"12 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":"125581546","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 main difficulties are overcome herein using a set of improved kernels in the usual Hallйn-type integral equations (these kernels had been developed in previous works, and were successfully incorporated into the aforementioned two-term theory analyses). We make a comparison of our MoM results to two-term theory results for the case of a 20-element array.","PeriodicalId":104769,"journal":{"name":"2010 International Conference on Mathematical Methods in Electromagnetic Theory","volume":"69 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114042760","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}
