The characterization of the 1-mm gap electrode device was carried out through experimental measurements and numerical simulations. The frequency time domain analyses demonstrate the adaptation of the proposed assembly up to 300 MHz. High voltage measurements and simulations were performed using an applied pulse duration of 10 ns and magnitude of 6.1 kV. This study proved the utility of this device for delivering pulses as short as 10 ns and achieving an electric field magnitude of 6 MV/m. This device can be used for real-time investigations of biological samples.","PeriodicalId":366020,"journal":{"name":"2016 IEEE Middle East Conference on Antennas and Propagation (MECAP)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129084349","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 sources in the scene of interest is usually very small. Thus, sparse reconstruction becomes a good candidate to work with reduced data sets. Recently, coprime arrays have been proposed for source localization. In this paper, a moving coprime array configuration is implemented for DOA estimation under sparse reconstruction framework. The proposed array uses only one antenna element. The antenna moves along the array axis to cover certain locations specified by the conventional coprime array. A stepped frequency continuous wave (SFCW) signal over ultra-wideband (UWB) is used. A microcontroller is used to control the movement and the data acquisition from the vector network analyzer to the computer. Two main advantages arise out of this approach. First, the complexity in terms of the total number of antenna elements and receivers needed to implement the array is reduced. Second, the mutual coupling effect is eliminated since only one antenna is active at a time. Experimental results in real scenarios were conducted to validate the proposed configuration. It is shown that coprime sampling is superior to uniform sampling with the same number of elements. The impact of the antenna directivity is highlighted.","PeriodicalId":366020,"journal":{"name":"2016 IEEE Middle East Conference on Antennas and Propagation (MECAP)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114286555","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}

This is followed by comparing the AF of CPA of ideal (isotropic) elements with an actual implementation considering Dipole elements.

Massive MIMO is expected to be one of the pillars of fifth generation (5G) and beyond cellular systems. In fact, with millimeter wave (mmWave) communications, a large number of antenna elements can be used to form large arrays of reasonable sizes. This entails significant challenges that need to be overcome in practical implementations.

The proposed structure is a silver gear structure that is expected to make good enhancement of light absorption inside the semiconductor forming the photovoltaics (PV) in the visible range of frequencies (200-800 THz). The nano antenna particle is embedded inside the photovoltaics and produces highly confined near-field around the nanoparticle and withing the semiconductor. The extinction cross-section of the proposed nanoparticle in vacuum has been calculated versus the wavelength. Also, the modes of fields are studied and finally the effect of embedding this gear nanoparticle in a silicon photovoltaic is investigated by comparing its absorption with the conventional disk nanoparticle.
