Groundwater provides roughly 43% of the water used globally for irrigated agriculture. Understanding, predicting, and managing the environmental processes that define the natural capital of Earth's changing groundwater is one of the most pressing soc

This article discusses the implementation of a 2-D pseudospectral time-domain (PSTD) full-wave simulator for solving large-scale low-frequency (e.g., HF) electromagnetic (EM) scattering problems with the application of radar sounding of planetary sub

The magnetoquasistatic (MQS) field coupling theory is presented for long ranges between a transmitting device located outdoor to a receiving device located indoor. The theory is validated based on measurements in a large indoor house environment ( $>

An electrically small electro-quasi-static exciter is demonstrated using a counter-wound normal-mode helical antenna. The arms are counter-rotated to cancel the generation of magnetic fields in the quasi-static regime. The field equations are derived

Magnetoquasistatic (MQS) fields are not significantly disturbed by dielectrics and have been demonstrated for accurate position sensing in GPS-denied or occluded indoor environments. Previous experiments utilizing the Through-the-Wall technique have

The surface of Mars has been well mapped and characterized, yet the subsurface — the most likely place to find signs of extant or extinct life and a repository of useful resources for human exploration — remains unexplored. In the near future thi

We present the magnetoquasistatic (MQS) coupling theory between a mobile transmitting device located within a building (indoor) and a fixed receiving device located outside the building (outdoor), with the assumption that the building can be approxim
