1. A comprehensive study of resistor-loaded planar dipole antennas for ground penetrating radar applications
Abstract : Ground penetrating radar (GPR) systems are increasingly being used for the detection and location of buried objects within the upper regions of the earth’s surface. The antenna is the most critical component of such a system. READ MORE

2. Analysis of Resistor-Loaded Bow-Tie Antennas for Ground Penetrating Radar Applications
Abstract : Ground penetrating radar (GPR) systems are increasinglybeing used for the detection and location of buried objectswithin the upper regions of the earth's surface. Numericalsimulation of such systems plays an important role in thedevelopment of GPR hardware and signal processingtechniques. READ MORE

4. Electromagnetic Waves in Media with Ferromagnetic Losses
Abstract : The operation of a wide variety of applications in today's modern society are heavily dependent on the magnetic properties of ferromagnetic materials and their interaction with electromagnetic fields. The understanding of these interactions and the associated loss mechanisms is therefore crucial for the improvement and future development of such applications. READ MORE
