A procedure for the generation of ideal ¨oltage source models whose effecti¨e generator impedances are matched to the transmission lines they dri¨e is presented. These matched source models offer impro¨ement o¨er existing ideal ¨oltage source models for the computation of dri¨ing point impedances. T

## Abstract MR imaging and spectroscopy requires RF fields of high homogeneity. Quadrature volume coils meeting this requirement include the birdcage coil and the TEM resonator. We describe here a quadrature volume coil designed around a modified coaxial transmission line in which multiple inner co

In this paper, we present a new transmission line transformer which is capable of matching a load resistance RL to a given source of internal resistance R , in a frequency independent manner. This matching can be made perfect at all frequencies if R J R , = 4 ; for R J R , # 4 , the matching can sti

An iterati¨e method for the design of tapered transmission lines is described. The method applies the Fourier transform to a ( ) linearized Riccati equation to yield a spectral function Q k which relates to a frequency spectrum with a corresponding characteristic impedance profile.

## Abstract Impedance matching of a loaded microstrip transmission line is performed by using only parasitic elements. By the term “parasitic” matching element we mean that there is no physical connection between the conductors of the matching subsystem and the conductors of the main circuit. We co

## Abstract A novel concept based on the use of higher‐order harmonic resonances in a transmission‐line resonator is introduced for the design of high‐frequency RF coils at high and ultrahigh fields, where conventional RF coil designs present difficulties and limitations. To demonstrate this concep
