  • Wideband and low loss metamaterials for microwave and RF applications: Fast algorithm and antenna design

    Publication Year: 2008, Page(s): 7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (100 KB) | HTML iconHTML

    The paper is split into two major parts: (1) the first is to look into the EM wave properties in metamaterials and to develop an efficient solvers for their designs; and (2) the second is to try to design the metamaterials for antenna applications. For the efficient algorithms developed, the integral equation solvers accelerated using the adaptive integral (equation) method (AIM) and also the pre-... View full abstract»

  • FDTD Modeling of electromagnetic cloaks

    Publication Year: 2008, Page(s):12 - 13
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (63 KB) | HTML iconHTML

    In this paper, a radial-dependent dispersive FDTD method is developed to model metamaterials based on coordinate transformation. Such artificial materials have been applied in developing electromagnetic cloaking devices, plane wave concentrators and wave polarization rotators. By using the time-domain numerical technique, the transient response and operational bandwidth of the proposed metamateria... View full abstract»

  • Tunable plasmonic metamaterials based on fractal geometry

    Publication Year: 2008, Page(s): 15
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (221 KB)

    Surface plasmon polaritons (SPPs) are elementary electromagnetic (EM) excitations bounded at a metal/dielectric interface. Due to two important features - local field enhancement and subwavelength resolution capability - of the SPP, it has attracted considerable attention recently and many SPP-based applications were proposed or demonstrated. However, for a natural material, its plasmon frequency ... View full abstract»

  • Effective 1-D material properties of coplanar-waveguide-based EBG- and meta-materials

    This paper aims to give unified characterization of coplanar-waveguide-based 1D electromagnetic-bandgap (EBG) and metamaterial in terms of two fundamental per-unit-length (PUL) transmission parameters, i.e., characteristic impedance and propagation constant. In analysis, a full-wave self-calibrated method of moments (MoM) is applied to de-embedding these two PUL parameters from simulation of two-p... View full abstract»

    In this presentation, I will analyze the image focusing, rotation, lateral shift, as well as the image magnification with sub-wavelength resolutions through differently designed structures of compensated anisotropic metamaterials. The verifications of all the proposed structures by full wave electromagnetic simulations will also be demonstrated. Utilizing the proposed structures, planar optical im... View full abstract»

  • New transport regime and Zitterbewegung effect in two-dimensional photonic crystal

    Publication Year: 2008, Page(s):29 - 32
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1726 KB) | HTML iconHTML

    A new transport regime of electromagnetic wave in two-dimensional photonic crystal near the Dirac point has been demonstrated by exact numerical simulation. In this regime, the conductance of photon is inversely proportional to the thickness of sample, which can be described by Dirac equation very well. Based on it, some unusual beating effects, which can be regarded as optical analogue to Zitterb... View full abstract»

  • Investigations of metamaterials for microwave frequency in time-domain

    Summary form only given. Metamaterials, specially, metamaterials for microwave by composite right-left-handed transmission line (CRLH-TL), are studied frequency in frequency-domain. For example, it was studied by transmission-reflection characteristics from S-parameter. But it is difficult to know clearly the relationship of phases, of group velocity, of phase velocity, and the wave propagation pr... View full abstract»

  • Slow light and omnidirectional resonances in the metamaterial-based multi-layer structures

    Publication Year: 2008, Page(s): 36

    Metamaterials, with effective negative permittivity and/or negative permeability, have paid much attention in recent years. We present the results on slow light and omnidirectional resonances in the metamaterial-based structures. We have found that the group velocity vanishes in the planar and cylindrical waveguides consisting of the left-handed metamaterial core and the single-negative-permittivi... View full abstract»
