  • Analysis and applications of multiple coupled line structures in an inhomogeneous medium

    Creator:
    Chin, Youn Kang
    Abstract:
    The general expressions for finding the network functions, e.g., the immittance and the scattering parameters, of a general, uniformly coupled n-line structure in an inhomogeneous medium are derived in terms of the normal mode parameters of the system. These are used to compute or to derive the explicit expressions for...

  • Quasi-TEM and full wave numerical methods for the characterization on microstrip discontinuities

    Creator:
    Hill, Achim
    Abstract:
    Static and dynamic numerical techniques which are suited for the analysis and simulation of various planar microstrip components encountered in hybrid and monolithic microwave integrated circuits are presented. The static analysis makes use of an excess source formulation in conjunction with an efficient mathematical treatment to extract the discontinuity parameter...

  • Nonsymmetrical coupled microstrip lines for applications as ideal directional couplers

    Creator:
    Emery, Timothy R.
    Abstract:
    A variational integral method in the Fourier transform domain is used to calculate the characteristic normal mode parameters of a coupled pair of nonsymmetrical microstrip transmission lines in an inhomogenous dielectric medium under quasi-TEM conditions. These together with the theory of such structures are used to show that ideal directional...

  • Propagation characteristics of strapped coplanar waveguides

    Creator:
    Hinz, Robert C.
    Abstract:
    The propagation characteristics of a new coupled fin line structure, with asymetrical, rectangular, top and bottom housings, is evaluated by using the modal analysis technique. The boundary Green's function of the structure, relating the surface currents to the electric fields is derived by using this technique. The propagation characteristics, i.e....

  • Analysis of interacting discontinuities in microstrips by mode-matching technique

    Creator:
    Kapoor, Sunil
    Abstract:
    In this thesis a numerical technique to model general microstrip asymmetric and multiple step discontinuities is presented. The method is based on a magnetic wall waveguide model that is assumed to be valid for describing the electromagnetic fields associated with the microstrip line and in the vicinity of microstrip discontinuities....

  • Computational methods for the quasi-TEM characteristics of fundamental MIC planar structures

    Creator:
    Lee, Hyuckjae
    Abstract:
    Accurate and efficient computational methods to evaluate the quasi-TEM parameters of various planar structures such as microstrips, coplanar lines and coplanar waveguides are developed. The characteristic parameters of all these structures which are used extensively in microwave integrated circuits for applications as transmission lines and other circuit elements are computed...

  • Characterization of coupled microstrip structure using FDTD

    Creator:
    Kim, Yoonsuk
    Abstract:
    A new CAD-oriented methodology for the full-wave broadband characterization of coupled microstrip structures for RF/microwave and high-speed digital circuits is presented. The characterization methodology is based on the finite difference time domain (FDTD) technique combined with a systematic extraction procedure using the normal mode approach and multiport network concepts. The...

  • Analysis and applications of layered multiconductor coupled slot and strip-slot structures

    Creator:
    Luo, Sifen
    Abstract:
    Layered multiconductor coupled slot and strip-slot structures are characterized by introducing the full-wave modal analysis as well as the quasi-TEM spectral domain technique. In the modal analysis, the electric and magnetic fields are constructed in terms of modal fields in different regions. Application of the boundary conditions at interfaces for...
