Parabolic equation method (PEM) represents one-way propagation and is widely used in two-dimensional (2D) radio wave/ground wave propagation modeling. It takes the earth's curvature, atmospheric ...

Abstract: This paper proposes a real-time prediction of duct using a genetic algorithm (GA)-based refractivity from clutter (RFC) method and the parabolic equation (PE) method. Three dates with duct ...

Parabolic reflectors are pretty handy devices. Whether you’re building a microwave antenna or a long-distance directional microphone, suitable commercial dishes aren’t that hard to come by.

There are better ways to build a radio telescope in your back yard, but the thought of having a gigantic parabolic dish out back, peering into the heavens, has stuck with me. I’ve even designed ...

Schematic diagram of a parabolic reflector. Incoming sound is directed to the microphone placed at the focus of the parabola-shaped reflector. The property of the parabolic shape to reflect all sound ...

is a solver for parabolic partial differential equa- tions over a 1d space (L) and a given time (T). The solver can be used to plot or analyse the results to the heat equation over time. The solver ...
