Optimal array factor radiation pattern synthesis for linear antenna array using cat swarm optimization: validation by an electromagnetic simulator Article

Gopi RAM, Durbadal MANDAL, Sakti Prasad GHOSHAL, Rajib KAR

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 4,   Pages 570-577 doi: 10.1631/FITEE.1500371

Abstract: In this paper, an optimal design of linear antenna arrays having microstrip patch antenna elements has been carried out. Cat swarm optimization (CSO) has been applied for the optimization of the control parameters of radiation pattern of an antenna array. The optimal radiation patterns of isotropic antenna elements are obtained by optimizing the current excitation weight of each element and the inter-element spacing. The antenna arrays of 12, 16, and 20 elements are taken as examples. The arrays are designed by using MATLAB computation and are validated through Computer Simulation Technology-Microwave Studio (CST-MWS). From the simulation results it is evident that CSO is able to yield the optimal design of linear antenna arrays of patch antenna elements.

Synthesis and thermosensitive behavior of dextran graft copolymers containing poly (N-vinylcaprolactam) side

SHI Huangying, CHEN Wenjuan, ZHANG Liming

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 1,   Pages 72-75 doi: 10.1007/s11705-007-0015-7

Abstract: New graft copolymers were synthesized by grafting N-vinylcaprolactam onto dextran. Their composition and structure were investigated by elemental analyses, infrared spectra and thermogravimetric analyses. By optical transmittance measurements, it was found that the aqueous solutions of these graft copolymers showed a temperature-dependent transmittance change due to the introduction of thermosensitive poly (-vinylcaprolactam) graft chains. Moreover, the lower critical solution temperature (LCST) of the graft copolymer in aqueous solution was dependent on its grafting extent and concentration. The LCST value was found to increase with the increase of the grafting extent and decrease with the increase of the copolymer concentration. With these stimuli-response properties, such polysaccharide derivative may hold potential applications in biomedicine and biotechnology.
