A position/vector transformation library, making it easy to manipulate 3D coordinate systems. Vectors can be in Cartesian, Spherical, or Cylindrical format, and the library includes matrix utilities ...

Abstract: In an active radar-tracking system, the target-motion model is usually modeled in the Cartesian coordinates, while the radar measurement usually is obtained in polar/spherical coordinates.

Abstract: Spherical transmission lines provide the rigorous network representation of radiation problems. In this work, the generalized network formulation is applied to the problem of radiation from ...

According to the Segré-Silberberg effect, spherical particles migrate to a lateral equilibrium position in parabolic flow profiles. Here, for the first time, the corresponding equilibrium velocity is ...

This article provides a closed form solution to the telegrapher’s equation with three space variables defined on a subset of a sphere within two radii, two azimuthal angles and one polar angle. The ...
