In this paper, three-dimensional (3D) metamaterials are used in near field wireless power transfer (WPT) system for efficiency enhanced. The 3D metamaterial structure is composed of 4×4×1-array of five-turn spiral resonators. The WPT with bulk metamaterial is investigated theoretically, experimentally, and by simulation. To verify the enhancement of the WPT system by using 3D metamaterial, the four-coil systems integrated with and without bulk metamaterial are investigated by vector network analyzer (VNA). As a result, the maximum efficiency improvement of 20% is obtained with the 3D metamaterials at 1.5m transfer distance. At the same time, the range of efficient power transfer can be greatly extended.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"67 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":"114380235","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}

They were used as bandpass filters in the triplexer design to meet three different bandwidths in 2.3, 2.5, and 3.5 GHz bands.

In order to meet the communication requirements of the future safety computer, by analyzing the characteristics of communication data and the main factors influencing real-time performance in the safety computer, the constrained multilevel priority scheduling strategy is proposed. This strategy consider the constraint relation between data frames under the conditions of meeting the multi-priority when the data to be transmitted. Through the network calculation method, the communication delay of different data stream in the two modes is analyzed. The improved scheduling strategy shortens the maximum delay of emergency safety critical data stream by 22.5% in the current safety computer under the condition of increasing the limited delay of non-safety critical data stream, so the strategy can effectively improve communication real-time performance of emergency safety critical data stream.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"37 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":"117063371","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 number of devices, which are deployed on the network edges, increasing sharply. It resulted in numerous data in sensing layer, and leads to network heavily loaded & high delay. Edge computing has its advantage “close to data source”, which can reduce the network latency significantly, but the ability of computing limited. In this paper, we propose a novel weight-polling based task classification scheme towards flexible computing. According to the demand characteristics of resources, tasks are divided into three types: computational, communication and storage. The goal of scheme is to trade off the costs between data transmission of cloud computing and compute of edge devices. The experimental results show that flexible computing can effectively reduce the network delay and response time, improve the resource utilization and task throughput, so as to take into account both the advantages of cloud computing and edge computing, to achieve the fairness of task scheduling.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"101 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":"132718845","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 capability of the existing method is limited due to the model error caused by approximated dictionary matrix calculated using ray optics method. In this paper, multipath propagation is calculated by finite-difference time domain (FDTD) technique and then compensated to obtain the linear inverse model correctly. Afterwards, sparse reconstruction is used to solve this linear inverse problem. Numerical results demonstrate that the proposed approach yields high resolution image free of multipath ghosts, thus allowing to increase the signal-to-clutter ratio image.","PeriodicalId":320947,"journal":{"name":"2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE)","volume":"3 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":"132975790","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}

On this basis, the influence of sea slick's damping on Doppler spectra of backscattered echoes from contaminated “choppy wave model” (CWM) nonlinear sea surfaces is investigated by comparison with the Doppler spectra of clean sea surfaces. Numerical simulations show a narrowing of the Doppler spectra of contaminated sea surfaces compared with those of clean sea.

The phase difference between the reflected wave from artificial magnetic conductor (AMC) and perfect electric conductor (PEC) is 180°. So its radar cross section is very low. If the target covered by this type of AMC, its RCS can be reduced significantly, which brings difficulty for detection. To detect low RCS target, the time domain scattering from AMC surface is studied. It is found that the amplitude of the scattering is very large in the beginning. And it becomes low after a while. We call this phenomenon the time domain electromagnetic sputtering effect. In this paper, the time domain backward scattering is analyzed by the equivalent circuit method.
