  • 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 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...

  • 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...

  • Field theoretic analysis of a class of planar microwave and opto-electronic structures

    Creator:
    Hahm, Yeon-Chang
    Abstract:
    With increasing operating frequencies in CMOS RF/microwave integrated circuits, the performance of on-chip interconnects is becoming significantly affected by the lossy substrate. It is the purpose of the first part of this thesis to develop a rigorous field theoretic analysis approach for efficient characterization of single and multiple coupled interconnects...
