An optical simulation of poly(3-hexylthiophene) (P3HT)/Si nanowire array (NWA) hybrid solar cells was investigated to evaluate the optical design requirements of the system by using finite-difference time-domain (FDTD) method. Steady improvement of light absorption was obtained with increased P3HT coating shell thickness from 0 to 80 nm on Si NWA. Further(More)
— Based on the statistical property of SAR image speckle noise and the property that the multiscale geometric analysis can capture the intrinsic geometrical structure of image, combining curvelet transform with BivaShrink denoising model, a method of SAR image denoising based on curvelet domain is presented in this paper. According to calculation of(More)
This paper presents an efficient method for analyzing the performance of dielectric radomes illuminated by phased array antennas with wide scanning angles using volume integral equation based on the method of moment (VIE-MoM). A concise relationship between the unknown electric density flux of VIE-MoM and the scanning angle is derived and applied to avoid(More)
