The cubic dipole cells are used to discretize scatterers. Furthermore, this paper novelly considers the role of the irregular parts of the scatterers' edge. The backscattering cross section and the bistatic scattering cross section of the cluster of needles calculated by DDA algorithm are compared with the results obtained by the analytical algorithms of the Generalized by Rayleigh-Gans Approximation (GRGA) algorithm and Thin Dielectric Cylinder (TDC) algorithm. In addition, the comparison of the results with considering the parts in the edge of scatterers and without considering it is presented in this paper. The simulation demonstrates that the numerical solution is better than the analytical solution, but the analytic solution is more efficient in the backscattering and bistatic scattering of a cluster of needles. Moreover, the algorithm considering the portion in the edge of the scatterers can improve computational efficiency and reduce storage space. In conclusion, the study for bistatic scattering of dense scatterers by taking into account the parts in the edge of scatterers are meaningful in the sight of computational efficiency and accuracy.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115751277","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}

In order to filter noise of pulmonary CT images and keep the edge and texture signal in images, this paper presents a pulmonary CT images denoising algorithm based on Curvelet transform. First, algorithm carries on Curvelet transform to noisy pulmonary CT images. Then algorithm constructs direction criteria and scale criteria for noise determination in the curve wave domain, and noisy pulmonary CT images is denoised. At last, curved wave inverse transformation is performed and the denoised pulmonary CT images is obtained. Experimental results show that this method has better effect for keeping edge and visual smooth, compared with traditional curvelet threshold shrink method.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124838135","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 human phantom body is filled with absorbing material instead of tissue fluid to prevent cavity effect and save the cost of manpower and money. An electric field probe is put in the abdominal cavity of human phantom body to receive the electromagnetic waves. Then electric field value of the abdominal cavity is measured with or without electromagnetic shielding garments on human phantom body. After comparing the mesured shielding effectiveness (SE) of different garments and the fabrics made into those different garments, the performance between garments and their corresponding fabrics are also discussed. It concludes that the design style is the determining factor to affect the SE value rather than metal fiber content. The research results can be applied to production and trade.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114139640","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 beam direction can be controlled by changing the effective width of the waveguide. The antenna structure contains two rows of vias located along the waveguide on each side. The outer row of vias is fixed. The spacing between the adjacent vias of the inner row can be changed, so the effective width of the waveguide is varied, therefore the beam angle of the antenna is controlled. The results of full-wave simulation of the antenna show the ability of the main beam controlling, which can be adjusted from 36° to 70° at 5.8 GHz for the parameters given in this paper.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128999020","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 discussed P-band SIW horn antenna has low profile and end-fire radiation pattern, so it is an alternative scheme when the dimension of antenna mounting platform is limited or the end fire radiation beam is required for the practical engineering application. This paper designed and simulated a SIW horn antenna fed with coaxial cable and the working frequency was 500MHz. The effects of substrate thickness on the performances of the SIW horn antenna was considered and simulated in order to diminish the height of SIW horn. The metal diaphragms were loaded at the side walls of the SIW horn, which were used to realize the impedance matching. The designed SIW horn antenna was simulated and optimized by use of full wave electromagnetic simulation software. The simulated voltage standing wave ratio (VSWR) of designed SIW horn antenna was less than 2 at the central frequency and directivity of the simulated SIW horn antenna is higher than 3dBi, and the end fire radiation pattern is also achieved. The height of the designed SIW horn antenna was 25 mm and low profile characteristic was also attained. Yet the band width of designed SIW horn antenna is narrow, so it is suitable for the case with narrow frequency range. The research results in this paper can provide certain technical references for some practical engineering applications.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116473838","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}
