Radiowave Propagation Techniques
We are interested in developing propagation prediction techniques in various environments such as Rough Surface, Indoor and Outdoor Wireless Communications, Tunnels, Uneven Terrain, Inhomogeneous atmosphere, etc. The goal is to come up with efficient methodologies to make reasonably accurate predictions.
Stochastic Methods for Wave Propagation
Some of the topics we are exploring in this connection are stochastic formulation of Parabolic Wave Equation, Wave and Telegraph Equations and Material Boundaries, Absorbing Boundaries, etc. More recently we have been developing stochastic based techniques for estimating wildlife location coordinates using time-series of power measurements from nano-tages attached to the animal body. The red trace in the figure below shows the polar coordinates of the bird as predicted by a Kalman filter. Radial axis is in km and the angle corresponds to the azimuth angle in a plane.
