  • Quasi-static design of electro-optic modulators by the method of lines

    Creator:
    Myers, Robert A. (Robert Allan), 1962-
    Abstract:
    Coplanar microstrip structures placed on dielectric substrates are used as high frequency electro-optic modulators. The method of lines, a mathematical technique for solving partial differential equations, has been applied to solve for the propagation characteristics of such a configuration. It has been determined that simple transmission line models are adequate...

  • 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...

  • 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...

  • 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....

  • Analysis and modeling of discontinuities and inter-element coupling in passive microwave integrated circuit components

    Creator:
    Thorburn, Michael Arthur
    Abstract:
    Accurate, efficient and general computational techniques are developed to evaluate the scattering parameters of passive microstrip components composed of discontinuities in microstrip transmission lines on general two layer substrates with single and two level metallization. An open domain model is used. The Electric Field Integral Equation is examined and the...

  • 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...

  • 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 and modeling of planar microstrip spiral inductors on lossy substrates

    Creator:
    Lutz, Richard D.
    Abstract:
    The advent of low-cost RFIC's fabricated in Silicon-based technologies has led to the use of monolithic lumped elements which are located on-die. While it is clearly advantageous to have a high degree of integration and thus fewer off chip elements, parasitic losses due to semiconducting substrate effects can be a...

    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...

    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...
