Abstract gprMax is open source software that simulates electromagnetic wave propagation,
using the Finite-Difference Time-Domain (FDTD) method, for the numerical modelling of …

Ground penetrating radar (GPR) is a special type of radar, which uses electromagnetic (EM)
wave to detect the buried objects in the shallow subsurface. The overall efficiency and …

Very few researchers have developed numerical models of ground-penetrating radar (GPR)
that include realistic descriptions of both the antennas and the subsurface. This is essential …

As ground‐penetrating radar (GPR) technology improves, there is an increasing demand for
more sophisticated and detailed interpretational tools. Numerical modelling has become …

We present a comprehensive study of a new method to reconfigure, tune, and/or program
antennas and radio-frequency (RF) devices. The method consists of using electrical signals …

In this paper, three types of novel bowtie antennas with round corners are presented and
studied carefully, including quadrate, rounded-edge and triangular shapes, which have …

Bowtie antennas are ubiquitous in practical ground-penetrating radars. In spite of having a
wide impedance bandwidth, boresight gain of these antennas is small and the main beam …

A novel exponentially tapered TEM horn antenna is presented. It is fed directly by a coax
through a compact transition section and possesses a wide bandwidth, good radiation …

This letter presents a new approach for the design of a multiresonant printed bowtie
antenna. Several techniques were attempted to obtain one antenna which is operational in …

This paper discusses the challenges in characterizing electromagnetic (EM) waves
propagating through inhomogeneous media, such as reinforced cement concrete and hot …
