A new wideband Wilkinson Power Divider which use the nonuniform substrate integrated waveguide (NSIW) method is presented in this paper. This structure utilizes NSIWs instead of the uniform quarter wavelength SIWs in conventional Wilkinson power divider. The proposed structure is analyzed by odd and even mode analysis. The proper NSIW section widths can be extracted by using even mode while the...

A wavelet approach to the analysis of nonuniform high-speed interconnects with frequency dependent parameters is presented in this paper. The nonuniform interconnects are modeled by the use of nonuniform multiconductor transmission line equations in the frequency domain. Two different methods are proposed here (differential and integral formulation): in both of them the space variable is expand...

The solution to the telegrapher equations is often presented as a D’Alembert expression for the voltage in terms of the voltage at a previous time or for the current in terms of the current at a previous time. In this paper, we present a complete solution for the coupled set of transmission-line equations such that the voltage or current is in terms of both the previous time voltage and current...

This paper is concerned with a discontinuous initial value problem for a dispersive hyperbolic equation where the dispersive term of the equation contains a large parameter. In the case of an equation with constant coefficients the initial value problem can be solved exactly leading to an integral representation which is expanded asymptotically. Nonuniform and uniform asymptotic expansions are ...

For a bandlimited function with polynomial growth on the real line, we derive a nonuniform sampling expansion using a special bandlimited function which has polynomial decay on the real line. The series converges uniformly on any compact subsets of the real line.

An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...

Abstract In this article, we introduce the notion of nonuniform biorthogonal wavelets on positive half line. We first establish characterizations for translates a single function to form Riesz bases their closed linear span. provide complete characterization biorthogonality scaling functions two multiresolution analysis and associated wavelet families in $$L^2({\mathbb {R}}^+)$$ <mml:math xmlns...
