1. Spectral broadening of 4 mJ femtosecond pulses using a bulk multi-pass cell
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index. READ MORE

3. Propagation of Radio Waves in a Realistic Environment using a Parabolic Equation Approach
University essay from Linköpings universitet/Teoretisk FysikAbstract : Radars are used for range estimation of distant objects. They operate on the principle of sending electromagnetic pulses that are reflected off a target. This leads to the propagation of electromagnetic waves over large distances. As the waves propagate, they are affected by several aspects that decrease the performance of the radar system. READ MORE

4. Simulation of a radar in Flames : a ray based radar model
University essay from Institutionen för informationsteknologiAbstract : In this report a radar model is modeled and implemented in a simulation framework called Flames. The focus is to investigate how and if electromagnetic waves emitted from the radar antenna can be simulated by different methods and how these methods can be implemented to work in real-time simulations.
