    Adiabatic Following in Two-Photon Transition 

    Nayfeh, Munir H.; Nayfeh, Ali H. (American Physical Society, 1977-03-01)
    The coherent interaction of two smoothly varying, near-resonant, two-photon pulses with a three-level system can be described by "two-photon damped Bloch equations" which are analogous to those for a one-photon transition ...

    Compressible Boundary Layers Over Wavy Walls 

    Lekoudis, S. G.; Nayfeh, Ali H.; Saric, W. S. (AIP Publishing, 1976)
    An analysis is presented of compressible viscous flows past wavy walls without restricting the mean flow to be linear in the disturbance layer. Linearization of the compressible disturbance equations results in a system ...

    Nonparallel Stability of Boundary-Layer Flows 

    Saric, W. S.; Nayfeh, Ali H. (AIP Publishing, 1975)
    The spatial stability of two‐dimensional incompressible boundary‐layer flows is analyzed using the method of multiple scales. The analysis takes into account the streamwise variations of the mean flow, the disturbance ...

    Effect of Relaxation on Self-Induced Transparency 

    Nayfeh, Munir H.; Nayfeh, Ali H. (American Physical Society, 1978-09-01)
    We derive an equation of motion of the Bloch-vector tipping angle and the area theorem in the presence of relaxation. We derive relaxation-dependent shifts in the equilibrium nπ areas. Part of these shifts depends on a ...

    Parallel_plate waveguide with sinusoidally perturbed boundaries 

    Nayfeh, Ali H.; Asfar, Omar R. (American Institute of Physics, 1974)
    The method of multiple scales is used to obtain a uniformly valid asymptotic expansion for the propagation of TM modes on a parallel_plate waveguide with perfectly conducting boundary surfaces that are sinusoidally perturbed ...

    Acoustic waves in ducts with sinusoidally perturbed walls and mean flow 

    Nayfeh, Ali H. (Acoustical Society of America, 1975)
    An analysis is presented of the propagation of acoustic waves in a hard-walled duct with sinusoidally perturbed walls and carrying mean flow. The results show that resonance occurs whenever the wavenumber of the wall ...

    Moiré Interferometry with White-Light 

    Post, Daniel (Optical Society of America, 1979-11-01)
    While high-sensitivity moiré interferometry requires monochromatic light, an auxiliary compensator grating removes the requirement. Experimental verification utilized white light for moiré interference of sensitivity 0.833 ...

    Nonlinear modulation of TM waves in a circular waveguide 

    Asfar, Omar R.; Nayfeh, Ali H. (American Institute of Physics, 1976)
    The method of multiple scales is used to derive a nonlinear Schrödinger equation for the temporal and spatial amplitude and phase modulations of TM waves in a perfectly conducting guide containing a nonlinear isotropic ...

    Simulation of multicorrelated random processes using the FFT algorithm 

    Wittig, Larry E.; Sinha, A. Krishna (Acoustical Society of America, 1975)
    A technique for the digital simulation of multicorrelated Gaussian random processes is described. This technique is based upon generating discrete frequency functions which correspond to the Fourier transform of the desired ...

    Secondary Instability in Boundary-Layer Flows 

    Nayfeh, Ali H.; Bozatli, A. N. (AIP Publishing, 1979)
    The stability of a secondary Tollmien–Schlichting wave, whose wavenumber and frequency are nearly one half those of a fundamental Tollmien–Schlichting instability wave, is analyzed using the method of multiple scales. Under ...
