Accessing the potentially habitable subsurface waters of Ocean Worlds requires a robotic ice probe (or “cryobot”) to traverse tens of kilometers of ice with temperatures ranging from ∼100 to 273 K. Designing and planning such a mission requires

Small satellites (smallsats) provide low-cost access to space and have historically been used for flight technology demonstrations and limited-function space science activities. Novel antenna technologies have enabled high-performance smallsat teleco

Computation of Radar Scattering From Heterogeneous Rough Soil Using the Finite-Element Method

Autor: J.J. van Zyl, Uday K. Khankhoje, Thomas A. Cwik

Publikováno v: IEEE Transactions on Geoscience and Remote Sensing. 51:3461-3469

A 2-D vector-element-based finite-element method (FEM) is used to calculate the radar backscatter from 1-D bare rough soil surfaces which can have an underlying heterogeneous substrate. Monte Carlo simulation results are presented for scattering at L

Electronic device scaling is ultimately limited by atomic dimensions. The simulation of electronic structure and electron transport on these length scales must be fundamentally quantum mechanical. This leads to computational models that account for f
