  • Parallel implementation of the DGF-FDTD method on GPU Using the CUDA technology
    Publikacja

    The discrete Green's function (DGF) formulation of the finite-difference time-domain method (FDTD) is accelerated on a graphics processing unit (GPU) by means of the Compute Unified Device Architecture (CUDA) technology. In the developed implementation of the DGF-FDTD method, a new analytic expression for dyadic DGF derived based on scalar DGF is employed in computations. The DGF-FDTD method on GPU returns solutions that are compatible...

  • Acceleration of the discrete Green's function computations
    Publikacja

    - Rok 2012

    Results of the acceleration of the 3-D discrete Green's function (DGF) computations on the multicore processor are presented. The code was developed in the multiple precision arithmetic with use of the OpenMP parallel programming interface. As a result, the speedup factor of three orders of magnitude compared to the previous implementation was obtained thus applicability of the DGF in FDTD simulations was significantly improved.

  • Accuracy of the discrete Green's function computations
    Publikacja

    - Rok 2012

    This paper discusses the accuracy of the discrete Green's function (DGF) computations. Recently closed-form expression of the DGF and its efficient numerical implementation were presented which facilitate the DGF applications in FDTD simulations of radiation and scattering problems. By carefully comparing the DGF results to those of the FDTD simulation, one can make conclusions about the range of the applicability of the DGF for...

  • Fast implementation of FDTD-compatible green's function on multicore processor

    In this letter, numerically efficient implementation of the finite-difference time domain (FDTD)-compatible Green's function on a multicore processor is presented. Recently, closed-form expression of this discrete Green's function (DGF) was derived, which simplifies its application in the FDTD simulations of radiation and scattering problems. Unfortunately, the new DGF expression involves binomial coefficients, whose computations...

  • Zjawisko przesłuchu w wieloprzewodowych prowadnicach koplanarnych
    Publikacja

    - Rok 2007

    Celem pracy jest analiza zjawiska przesłuchu na bliskim i dalekim końcu sprzężonych linii koplanarnych (ang. Coupled Coplanar Waveguides C-CPW) i sprzężonych linii koplanarnych z centralnie umieszczonym uziemionym paskiem (ang. Coupled Coplanar Waveguides with central Grounded Strip C-CPWGS) o skończonej długości przy pobudzeniu falą prostokątną. Wymagało to stworzenia modeli numerycznych rozpatrywanych prowadnic i poddania ich...
