Surface-wave group-delay and attenuation kernels
S U M M A R Y We derive both 3-D and 2-D Fréchet sensitivity kernels for surface-wave group-delay and anelastic attenuation measurements. A finite-frequency group-delay exhibits 2-D off-ray sensitivity either to the local phase-velocity perturbation δc/c or to its dispersion ω(∂/∂ω)(δc/c) as well as to the local group-velocity perturbation δC/C . This dual dependence makes the raytheoretical in...
متن کاملApplication of negative group delay active circuits to the design of broadband and constant phase shifters
The new phase-shifter configuration described in this report uses a negative group delay (NGD) active circuit. In this topology, a classical transmission line is set in cascade with an NGD circuit whose phase slopes are alike, but opposite, to get a constant and broadband phase shift. The proposed approach was validated through the design and measurement of a phase shifter, which exhibited a co...
متن کاملNegative group velocity and group delay in left-handed media.
The dynamics of wave propagation in media with negative index of refraction is analyzed through analytical calculations, simulations, and experiments. Using a free space setup, the transmission characteristics of two split ring resonator and strip wire left-handed media (LHM), designed for operation at K -band frequencies (18-26 GHz), are measured. The first LHM, which is 3 unit cells long in t...
متن کاملAnalog Group Delay Equalizers Design Based on Evolutionary Algorithm
This paper deals with a design method of the analog all-pass filter designated for equalization of the group delay frequency response of the analog filter. This method is based on usage of evolutionary algorithm, the Differential Evolution algorithm in particular. We are able to design such equalizers to be obtained equal-ripple group delay frequency response in the pass-band of the low-pass fi...
متن کاملDetection of Clicks Based on Group Delay
In this paper we present a novel approach for the automatic detection of clicks from recordings of beaked whales, based on the phase characteristics of minimum phase signals and especially using the group delay function. Group delay is estimated through the direct and first derivative of the Fourier Transform of a signal. A major advantage of the proposed approach is its robustness against addi...
