3D-position-sensitive detectors have demonstrated Compton imaging and excellent energy resolution at room-temperature operation. Unfortunately, Compton imaging is not practical at gamma-ray energies below 300keV in CdZnTe detectors, due to the higher probability of photoelectric absorption. To extend our imaging capabilities to lower energies, coded aperture masks have been applied to the Polaris...
Brief review of methods used for simulation of signal propagation in Wavelength-Division-Multiplexed (WDM) links is presented. Step-size distribution strategies used in Symmetrized-Split-Step-Fourier-Method (S-SSFM) are analysed. We propose novel Modified Logarithmic (ML S-SSFM) method of step-size distribution, which is a generalisation of logarithmic method used to suppress spurious FWM tones. In...
