Journal of Fluid Science and Technology, 2014 To examine pressure fluctuations in the near acoustic field, the wavenumber-frequency spectrum method was applied to the flow field around a square cylinder placed near a flat plate. Since the pressure fluctuations in the near field contain both acoustic

OCT wavenumber calibration with simple reference arm modification
, 2021 FD-OCT systems with non-uniform wavenumber sampling require calibration and resampling routines to achieve optimal axial resolution. We present a simple calibration procedure and provide all necessary algorithmic components for wavenumber

On plane thermoelastic waves in hemitropic micropolar continua
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019 The paper deals with the coupled heat transport and dynamic equations of the hemitropic thermoelastic micropolar continuum formulated in terms of displacements, microrotations and temperature increment which are to be determined in applied problems.

Complex Wavenumber Rossby Wave Ray Tracing
, 2019 This paper presents a methodology for performing complex wavenumber ray tracing in which both wave trajectory and amplitude are calculated. This ray-tracing framework is first derived using a scaling in which the imaginary wavenumber component is assumed

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
