    A number of issues relating to the implementation of a parallel finite-element program are discussed, including choice of programming language (principally FORTRAN90 versus C++), data-communication environment, matrix partitioner, and parallel preconditioner. Some results computed for an intricately shaped load in a microwave applicator are presented. View full abstract»

    We present a solution adopted for the Medicina antenna to carry out the fast, remote, and automatic change of many microwave receivers used for observation in radio astronomy. This new setup allows the capability to switch receivers located at the antenna's primary and secondary foci in a couple of minutes, without the need of manpower or equipment, and regardless of weather constraints View full abstract»

    Following discussions (Luo Lichun 1997) on the propagation and regularities of HF ground waves in urban areas in China, and processing the HF experimental data obtained from 1993 through 1997 and MF data obtained in 1995 and 1997 in Beijing, a new model for MF and HF ground-wave propagation in urban areas is proposed in this paper. The key novelty in the proposed model is the inclusion of three bu... View full abstract»

    This paper describes the physical models behind the various fading distributions applicable in wireless-communications systems, and presents the probability density functions, both for the signal envelope and for the power of the mobile radio signal. It addresses the problem of co-channel interference in terms of its mean value, for macrocellular and microcellular structures, and illustrates how t... View full abstract»

  • Design of a wideband miniature dielectric-filled waveguide antenna for collision-avoidance radar

    Publication Year: 2000, Page(s):34 - 40

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (204 KB)

    This article presents a theoretical and experimental study of the design of a miniaturized wideband dielectric-filled waveguide (DFW) antenna. The operational frequency is X band, i.e., 9.0⩽f⩽10.5 GHz. The desired bandwidth is 1.5 GHz. The antenna uses an air-gap matching network to reduce its high aperture reflection. In order to ease the integration with antenna circuits and to increase ... View full abstract»

    An efficient unified approach to the solution of a wide class of electromagnetic problems involving finite structures-including analysis of finite-array antennas (both transmission and reflection), scattering problems, and calculation of transmission-line eigenwaves-is presented. This approach is based on the fact that these problems can be described by the same mathematical tool, namely, convolut... View full abstract»
