Corrigendum: Multimode seismoelectric phenomena generated using explosive and vibroseis sources

Conductivity Dependence of Seismoelectric Wave Phenomena in Fluid-Saturated Sediments

Seismoelectric phenomena in sediments arise from acoustic wave-induced fluid motion in the pore space, which perturbs the electrostatic equilibrium of the electric double layer on the grain surfaces. Experimental techniques and the apparatus built to study the conductivity dependence of the electrokinetic (EK) effect are described and outcomes for studies in loose glass microspheres and medium-...

Nonlinear distortion of signals radiated by vibroseis sources

A model of nonlinearity of the contact between the vibrator baseplate and the ground is proposed to describe the distortion of vibroseis signals in the near-field. A thin layer between the baseplate and the soil exhibits a strong nonlinear response because of the difference in its rigidity between the compression and tension phases. The model allows for a quantitative description of the transmi...

Multimode dynamics and mode locking phenomena in QCLs

The dynamics of Quantum Cascade Lasers is investigated using modified MaxwellBloch Equations. It is shown that spatial hole burning and the Risken-Nummedal-Graham-Haken (RNGH) instability are the main causes for multimode operation in these semiconductor lasers. In 2000, R. Paiella et al. reported strong evidence of self-pulsations at the cavity roundtrip frequency in electrically pumped quantu...

Orthogonal sweeps of vibroseis

Vibroseis is a method that imparts coded seismic energy into the ground. The energy is recorded with geophones and then processed using the known (coded) input signal. The resulting time-domain representation of vibroseis data is an impulsive wavetrain with wavelet properties consistent with the coded input signal convolved with the earth’s reflectivity series. Historically vibratory seismic su...
