    Analysis of a cylindrical coupling structure
    (JOHN WILEY & SONS INC, 1999) Gorur, A; Duyar, M; Karpuz, C
    Coupled lines perpendicular to their cylindrical ground plane embedded in a cylindrical structure are proposed and analyzed CAD-oriented analytic formulas for investigating the quasistatic mode parameters and the coupling properties are derived with the even-odd mode analysis method based on the quasi-TEM approximation. Calculated mode impedances and coupling coefficients are observed to be sensitive to cylindrical curvature, especially for larger values of the spacing in the ground plane. Calculated results are compared,vith those obtained for a corresponding planar coupling structure. (C) 1999 John Wiley & Sons, Inc.

    Analysis of coplanar-coupled lines on a cylindrical substrate
    (JOHN WILEY & SONS INC, 2000) Karpuz, C; Duyar, M; Gorur, A
    CAD-oriented closed-form expressions are presented for calculating the quasistatic TEM parameters of coplanar-coupled lines on a cylindrical substrate. The effect of the curvature on the quasistatic parameters is discussed by using the formulas derived by the conformal mapping techniques. Comparisons have also been made between the present results and the results available in the literature for coplanar-coupled lines on a planar substrate. The results of this paper are in very good agreement with the results derived by the conformal mapping technique and the spectral-domain method for the planar one. (C) 2000 John Wiley & Sons, Inc.

    Analysis of coupled coplanar waveguides with V-shaped conductor backing using conformal-mapping method
    (IEE-INST ELEC ENG, 2000) Gorur, A; Karpuz, C; Duyar, M
    The V-shaped microshield coupled parallel coplanar waveguides. a new type of the coupled parallel coplanar waveguide (CP CPW). is proposed. Closed-form expressions are presented for calculating the quasistatic parameters of this coupled structure bq using conformal-mapping techniques. The effect of the V-shaped conductor backing on the coupling between CPWs is also discussed. Comparisons are made between the present numerical results and the spectral-domain method results available in the literature for a conventional CP CPW. In addition, the coupling coefficient of the present coupled CPW is shown to be significantly lower than that of a coupled parallel CPW.

    Analysis of cylindrical conductor-backed coplanar waveguides
    (JOHN WILEY & SONS INC, 2000) Karpuz, C; Duyar, M; Gorur, A
    CAD-oriented closed-form expressions are presented for calculating the quasistatic parameters of a conductor-backed coplanar waveguide (CBCPW) on a cylindrical substrate. The effect of the curvature on the quasistatic parameters is also discussed by using the formulas derived by the conformal mapping techniques. Furthermore, comparisons are made between the present results and the results available in the literature for CBCPW on a planar substrate and microstrip on a cylindrical substrate.

    Analytic formulas for calculating the quasistatic parameters of a multilayer cylindrical coplanar strip line
    (JOHN WILEY & SONS INC, 1999) Gorur, A; Duyar, M; Karpuz, C
    Fast, simple and accurate analytic expressions are derived for calculating the quasistatic TEM parameters of a multilayer cylindrical coplanar strip line (MC CPS). The effects of the dielectric materials on the quasi-TEM characteristics are investigated using the conformal mapping method The derived results are compared with those of a corresponding planar CPS. The curvature effects on the quasistatic parameters are also discussed. In addition, it has been observed that the effect of the inner substrate on the quasistatic parameters is much less than the outer substrate. (C) 1999 John Wiley & Sons, Inc.

    Quasi-TEM analysis of broadside-coupled V-shaped microshield coplanar waveguides
    (JOHN WILEY & SONS INC, 2000) Karpuz, C; Duyar, M; Gorur, A
    A new type of broadside-coupled CPWs (BC CPWs) is proposed using a V-shaped microshield CPW. Closed-form expressions are presented for calculating the quasistatic parameters of this coupled structure by using conformal mapping techniques. The effect of the V-shaped conductor backing on the quasistatic parameters and the coupling between CPWs are also discussed. Comparisons are made between the present numerical results and the results available in the literature for general BC CPWs. The coupling coefficient of the present BC CPWs is shown to be significantly lower than that of general BC CPWs. (C) 2000 Wiley & Sons, Inc.
