  • 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...

  • 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...

  • Analysis and modeling of electrically long MESFETS and coupled schottky lines

    Creator:
    Mohammed, Ahmed Sarhan
    Abstract:
    The properties of linear active coupled lines consisting of electrically long GaAs MESFET structures are investigated for possible applications as traveling-wave broad-band amplifiers. In addition, the nonlinear coupled Schottky lines are studied for applications as voltage tunable circuit elements. The analysis of the general active asymmetric coupled transmission lines in...

  • Nonuniformly coupled microstrip transversal filters for analog signal processing

    Creator:
    Hayden, Leonard.
    Abstract:
    An analog signal processing technique allowing arbitrary step response is presented. A transversal structure is used with nonuniform contradirectional coupling to provide continuous tapping. Sinusoidal and chirp responses are presented as examples implemented using this nonuniformly coupled microstrip structure.

  • Time domain simulation of multiconductor lossy transmission lines by the method of characteristics

    Creator:
    Orhanovic, Neven
    Abstract:
    A numerical technique to compute the time domain response of multiconductor lossy uniform and nonuniform lines terminated in general nonlinear elements is presented. The technique is based on the generalized method of characteristics. The method transforms the original system of transmission line equations into a system of ordinary differential equations....

  • 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...

  • 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...

    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....
