In one dimensional space with dispersion and nonlinearity, Gaussian envelope pulse modulated by optical carrier wave propagates physically reliable behavior for variety of electric field amplitudes, showing the spreading and the concentrating envelope wave form. By fast Fourier transform (FFT) of time domain wave form, dependencies of input pulse amplitude to the frequency spectrum after propagation are discussed. It shows that the spectra around carrier frequency is enhanced for larger input amplitude in nonlinear medium.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127410530","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 proposed antenna has a simple structure comprising of two folded strips and a rectangular ground plane. The antenna has been designed to cover six bands which are GSM850/900 (824–960 MHz), DCS 1800 (1710–1880 MHz), PCS 1900 (1850–1990 MHz), UMTS (1920–2170 MHz), and ISM 2450 (2400–2485 MHz). The designed antenna only occupies a small area of 50×20 mm2 on the system circuit board. By adjusting the strip length, the SAR is effectively reduced over all of the bands. The antenna is a promising candidate for incorporation into smart phones.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127444140","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}

Next, time domain scattering response is calculated from the frequency domain data by using the inverse Fourier transform. Numerical result shows that the degree of corrosion can be evaluated by the transient response from the reinforced bar in concrete structure.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124684659","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}

Owing to the large distance loss and weak diffraction, a channel in the millimeter wave band experiences a propagation loss that is much worse than that of a low frequency band. When the path loss in the millimeter wave band is measured, it is observed that the data is confined within a certain range owing to limitations. If the original least square is applied to the measurement data without considering the limitations of certain values, the path loss exponent can be underestimated. Therefore, both censoring and truncation environments should be taken into account in the regression model. In this paper, the performance of the Tobit maximum likelihood estimation, Heckman two-stage model and truncation regression model are compared with the ray-tracing simulation.","PeriodicalId":199234,"journal":{"name":"2017 IEEE International Conference on Computational Electromagnetics (ICCEM)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116854852","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}
