	1	Analysis of Focusing Orbital Angular Momentum Wave Using Fabry-Perot Cavity显示文摘One of the biggest obstacles to the application of orbital angular momentum(OAM)in the microwave field is its divergence problem.This paper presents a full analysis of generating and focusing OAM waves using original and improved Fabry-Perot(F-P)cavities.Utilizing combination of microstrip antenna and original F-P cavity,the gain of the OAM antenna is enhanced from 4.0 dBi to 9.3 dBi and the corresponding divergence angle is decreased from 41to 24.To further improve the performance of the OAM antenna,the improved F-P cavity is introduced.The simulated results show that the gain is further enhanced to 12.0 dBi and the divergence angle is further decreased to be 15.

	12	Pattern synthesis of antennas based on a modified particle swarm optimization algorithm显示文摘In order to overcome the drawbacks of standard particle swarm optimization(PSO)algorithm,such as prematurity and easily trapping in local optimum,a modified PSO algorithm is proposed,in which special techniques,as global best perturbation and inertia weight jump threshold are adopted.The convergence speed and accuracy of the algo-rithm are improved.The test by some benchmark problems shows that the proposed algorithm achieves relatively higher performance.Thereafter,the applications of the modified PSO in the radiation pattern synthesis of antenna arrays are presented.
