	Analysis of a diffractive microlens using the finite-difference time-domain method (EI CONFERENCE) 会议论文 OAI收割作者: Liu Y.; Liu H.; Liu H.; Liu H.; Liu Y. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 The finite-difference time-domain (FDTD) method is used as rigorous electromagnetic analysis model to calculate the field for a diffractive microlens (DML). The FDTD is used for the entire solution rather than using a near- to far-field propagation method to obtain the far-field energy distribution thus all the results are vector based. We derived a formula to calculate the magnitude of electric field which is time dependent and can be used to graphically show the light wave propagation and focusing process through a DML. Both the comparison and the integral methods are presented to obtain wave amplitude in full solution space and the distribution of light energy behind a DML is illustrated based on the wave amplitude. The formula of diffractive efficiency of the DML is derived from a time-averaged Ponyting vector which can indicate the propagation direction of light energy. Application of these formulations in the analysis of a DML example demonstrates the high accuracy and efficiency of our method. 2010 Society of Photo-Optical Instrumentation Engineers.
	DOA estimation algorithm of UWB signal based on unitary circuit array (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者: Zhang X.; Chen X.; Chen X.; Chen X.; Zhang X. 收藏 \| 浏览/下载：31/0 \| 提交时间：2013/03/25 In this contribution unitary circular array (UCA) techniques for estimating Direction of Arrival (DOA) of Ultra wideband (UWB) propagation signals are studied. Aiming at the defects of the DOA algorithms under uniform linear array (ULA) only can estimate 180 degree unfaintness angles in this paper the algorithms of one-dimensional and two-dimensional DOA estimation for UWB signals based on unitary circular array (UCA) are proposed. In order to estimate DS-UWB signals within 360 degree angles the UCA-CSM-RB-MUSIC algorithm is proposed which can estimate 360 degree unfaintness azimuth angles. 2010 IEEE.
