Periodic structures composed of quarter-wavelength or Helmholtz resonators have been widely used in the design acoustic metamaterials. An interesting phenomenon achievable through hybridization such is slow sound, which results from strong dispersion produced by local resonances. It gives rise to many applications as deep subwavelength sound absorbers metadiffusers. All proposed so far analyzed...

Analog Delay Line, " has been reviewed in final form. Permission, as indicated by the signatures and dates given below, is now granted to submit final copies to the College of Graduate Studies for approval. ABSTRACT High-speed synchronous interface circuits require that the controlling clock signals be accurately aligned. A dynamic de-skew circuit can be used to ensure good clock alignment acro...

Designing a non-ideal delay line (DL) with phase distortion in a transmitted-reference ultra-wideband system (TR-UWB) with an autocorrelation receiver (AcR) is a great technical challenge. Differing from the currently empirical design method of DL, in this paper a semi-analytic approach is proposed through Gaussian approximation of the expression for conditional bit error rate (BER), based on i...

In this paper, we present a methodology to explore and evaluate the crosstalk noise and the profile of its variations, and the delay of interconnects through investigation of two groups of interconnect structures in nano scale VLSI circuits. The interconnect structures in the first group are considered to be partially coupled identical lines. In this case, by choosing proper values for differen...
