Experimental demonstration of negative refraction and subwavelength imaging by left-handed composite metamaterials
(Cambridge University Press, 2006)We report a true left-handed (LH) behavior and focusing in a composite metamaterial consisting of periodically arranged split ring resonator (SRR) and wire structures. The magnetic resonance of the SRR structure is ... -
Improving the accuracy of a time lens
(Optical Society of America, 1997-11)A method for improving the accuracy of temporal imaging with an imperfect time lens is proposed. Signal distortion arising from complicated dispersion of the delay lines can be reduced considerably by appropriate choice ... -
Interpolation techniques to improve the accuracy of the plane wave excitations in the finite difference time domain method
(Wiley-Blackwell Publishing, Inc., 1997-11)The importance of matching the phase velocity of the incident plane wave to the numerical phase velocity imposed by the numerical dispersion of the three-dimensional (3-D) finite difference time domain (FDTD) grid is ...
