1. A comprehensive study of resistor-loaded planar dipole antennas for ground penetrating radar applications
Sammanfattning : 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. LÄS MER
2. Analysis of Resistor-Loaded Bow-Tie Antennas for Ground Penetrating Radar Applications
Sammanfattning : 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. LÄS MER
3. Optimal Near-field Antenna Apertures in Lossy Media
Sammanfattning : Antennas are traditionally designed for far-field applications such as wireless communications, radar, etc., where the antenna systems interact with other systems and objects which are located in the far-field zone of the antennas. LÄS MER
4. Electromagnetic Waves in Media with Ferromagnetic Losses
Sammanfattning : 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. LÄS MER
5. Net-based Learning and the mStar Environment
Sammanfattning : This licentiate thesis focuses on how to design a robust and flexible environment for net-based learning. The environment is required to be scalable for large groups, robust over lossy networks, flexible to meet different learning scenarios, and support interactivity. LÄS MER
