Two configurations of DLAs are considered, namely: two-shell circularly-layered lens excited by a horn antenna and shaped homogeneous flat-bottom lens excited by an array of printed feeds. Synthesis of the antennas is carried out in the 2-D formulation using highly-efficient in-house softwares based on rigorous mathematical approaches (Mie-type series solution for the former and Muller's boundary integral equations for the latter). It is demonstrated that simultaneous optimization of lens and feeding structure parameters enables one to design a beam-switching DLA with improve performance characteristics (boresight directivity and steering ability) using standard low-loss dielectric materials.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114701676","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 the stratosphere, ozone critically controls the energy budget because it absorbs both solar UV and terrestrial IR radiation [1]. Spatial distribution and variations of the ozone content determine quantity and variations of the absorbed energy. Existing satellite instruments such as [2] can't provide both high resolution in horizontal plane and sufficiently dense data sets on concentration of ozone and ozone-related species (in the first place, chlorine and nitrogen oxides) over selected regions. So reliable ground-based instruments for monitoring of ozone and other minor atmospheric gases are necessary in addition to the satellites.","PeriodicalId":129834,"journal":{"name":"2010 INTERNATIONAL KHARKOV SYMPOSIUM ON PHYSICS AND ENGINEERING OF MICROWAVES, MILLIMETER AND SUBMILLIMETER WAVES","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130331855","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 ratio between the reactive and active power density has been calculated and analyzed at different planes in near-field region as well as along the axis normal to radiator aperture. It has been shown that, the reactive component of power flux density was absent in all planes of observation in sections |x|=|y| for the uniform amplitude distribution.

Following features of the setup such as total transmission losses below 2 dB from the source port to a resonator with a sample inside the cryomagnet; fine balance tuning between signal and reference channels affording up to 36 dB background signal suppression, linear-to-circular polarization conversion with a possibility to tune its phase, which allows effective suppression of reflected signal with respect to induction signal; switching between two microwave sources; and high power handling up to 20 Watt helped to reach high performance of the 9.2 Tesla DNP/NMR/EPR spectrometer.
