    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (462 KB)

    As wavelengths shrink to the mm and sub-mm range new capabilities from material sensing to imaging become possible, in addition to the larger bandwidths possible for large data communication. These new application possibilities from below 100GHz towards 1THz will be outlined in this talk. Paths of how to build cost effectively entire systems operating in the sub-THz frequency range using CMOS will... View full abstract»

    The main limitation of any chipless Radio Frequency Identification (RFID) system is the very short reading range. In this paper, we propose an Ultra Wideband (UWB) Reflectarray Antenna (RA) system with 2.2 GHz bandwidth centered at 6 GHz for the reader of chipless RFID applications. The proposed reader antenna system enhances reader sensitivity, reduces multipath effects, helps in tag localization... View full abstract»

    In this paper, a compact meander shaped defected ground structure (DGS) is applied to reduce the mutual coupling between elements of microstrip antenna array with 0.5 λ0 elements spacing. The proposed antenna array consists of two elements. Four meander shaped slots in the ground plane are used between elements to reduce the coupling between the array elements. The antenna is simulated usin... View full abstract»

    In this paper, a periodic structure of Complementary G-Shape Split Ring Resonator (CGSRR) is proposed to improve the gain of microstrip patch antenna (MPA). CGSRR is designed to work as a left-handed material (LHM) with negative permittivity and permeability in the frequency band of operation. The MPA is designed with 50 Ω co-axial probe feed to operate at frequency f0=10 GHZ. Ar... View full abstract»

  • Approximate electromagnetic cloaking and scattering of a dielectric cylinder with nonhomogeneous anisotropic cloaking material

    Publication Year: 2014, Page(s):41 - 50

    Cloaking refers to hiding a body from detection by surrounding it with a coating consisting of an unusual anisotropic nonhomogeneous material. The permittivity and permeability of such a cloak are determined by the coordinate transformation of compressing a hidden 2D or cylindrical body into a line. Some components of the electrical parameters of the cloaking material (ε,μ) are requi... View full abstract»

    In this paper we present modal analysis of a rectangular mm-waveguide loaded by a dielectric slab with a double-layered graphene sheet on the air-dielectric interface inside the waveguide. The surface impedance of the double layered graphene sheet can be controlled by the applied normal electric field. This property is found to be useful to control the boundary condition at the air-dielectric inte... View full abstract»
