In consideration of high heat transfer efficiency and stable combustion, a new type of microplanar combustor for micro-thermophotovoltaic (micro-TPV) system is proposed, in which the heat transfer is enhanced by staggered cylindrical array. The numerical

CAD of multilayer conformal cylindrical arrays
IEEE Antennas and Propagation Society International Symposium. 2001 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.01CH37229), 2002The new trends in the communication market are demanding wider bandwidths and consequently higher frequencies and higher bit rates. The traditional hardware development, based on the manufacture and measurement of test components, is too expensive and time consuming.

Numerical synthesis of cylindrical arrays
2012 6th International Conference on Ultrawideband and Ultrashort Impulse Signals, 2012The authors propose a synthesis method for cylindrical arrays. This method allows the calculation of the required amplitude-phase distribution within a given active sector of the antenna array, taking into account the directional properties of the radiating elements.

Layout-optimized cylindrical sonar arrays
Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005The cost of sonars scales to the number of active elements. Therefore, it is favorable to reduce the number of elements without loss in imaging quality. This is a combinatorial problem, but of such a large dimension, even for small arrays, that an exhaustive search is futile. In this work, we have found layout-optimized sparsed cylindrical arrays, i.e.

A cylindrical spiral patch array
2000 5th International Symposium on Antennas, Propagation, and EM Theory. ISAPE 2000 (IEEE Cat. No.00EX417), 2000A simplified approach to the analysis of the patterns of a cylindrical spiral patch array is presented. In this approach, the patch element is characterized using the cavity model and the radiation patterns for each element are calculated, assuming it is mounted on a flat surface, while the curvature effects are considered in the patterns of the array.

Sidelobe control in cylindrical arrays
IEEE Transactions on Antennas and Propagation, 1982Low sidelobe patterns in cylindrical arrays are synthesized through the use of an artificially created noise source environment. Pattern/excitation pairs are generated by an exact formal process which optimizes the array performance. For symmetric patterns this process minimizes the signal-to-noise power ratio. For optimum antisymmetric patterns the on-

Luminescent solar concentrators (LSCs) harvest solar radiation over large areas and concentrate this light onto edge-mounted solar cells. Here, we demonstrate that the addition of cylindrical optical fibers, along with a white scattering layer on the ...

Cylindrical Antennas and Arrays
2002Cylindrical arrays lie at the heart of the antenna systems of most major radio communication systems, including broadcasting networks, cellular 'phone systems and radar. In this book, the authors present practical theoretical methods for determining current distributions, input admittances and field patterns of a wide variety of cylindrical antennas ...
