On atmospheric humidity and acoustic ducts
The Journal of the Acoustical Society of America, 2018The development of various propagation ducting phenomena (elevated or surface) has been studied extensively for electromagnetic and electro-optical wave propagation. The influence of changes in temperature, pressure, and humidity gradients on the strength and geometry of the duct in the electromagnetic propagation problem is well-documented, and there ...

Doppler ducting of atmospheric gravity waves
Journal of Geophysical Research: Atmospheres, 1986Atmospheric gravity waves are subject to horizontal ducting in a stably stratified atmosphere that contains levels of wind maximum or minimum, quite apart from any superimposed consequences of vertical variation of stability and quite apart from the existence or otherwise of critical levels.

The PE solution of natural waveguides in atmosphere: ducts and elevated ducts
Proceedings of MELECON '94. Mediterranean Electrotechnical Conference, 2002The propagation phenomena through 2D surface duct-to-elevated duct transition is described in terms of parabolic equation (PE) method. The split step marching solution of the PE method is first compared with the reference solutions obtained from Helmholtz wave equation in longitudinally invariant surface duct problem and the excellent agreement between

Tracking atmospheric ducts using radar clutter: evaporation duct tracking using kalman filters
2007 IEEE Antennas and Propagation Society International Symposium, 2007This paper addresses the problem of tracking evaporation ducts in marine environments. The method tracks the evolution of the range and height-dependent index of refraction using the radar sea clutter. A split-step fast Fourier transform (FFT) based parabolic equation (PE) approximation to the wave equation is used to compute the clutter return in ...

FNN-Based Prediction of Wireless Channel with Atmospheric Duct
ICC 2021 - IEEE International Conference on Communications, 2021This paper proposes solutions to channel prediction with atmospheric duct based on feedforward neural network (FNN) modeling. Specifically, FNN-based model is to produce accurate prediction by directly learning from large database rather than depending on any assumption.
