Multi-ray channel modeling for programmable wireless environments in the terahertz band by Wenyu LUO, Hechao LIU

“…Terahertz communication system based on programmable wireless environment allowed programming customization of electromagnetic wave propagation in the most suitable ways for different wireless devices.It could not only improve serious fading,interference and non-line-of-sight problems,but also significantly enhance the security and privacy of the system.The channel modeling of terahertz wireless communication in programmable wireless environment was focused.Firstly,a multi-ray channel model for terahertz-band programmable wireless environment was established based on ray tracing technology as well as the propagation model of line-of-sight and non-line-of-sight.Then,based on the established propagation model,reflection coefficient,the broadband channel capacity under the water-filling power allocation algorithm and the RMS delayed extension were further studied.The simulation and analysis results show that the programmable wireless environment greatly reduces the influence of path loss and multipath fading in terahertz wireless transmission through active interference in electromagnetic wave transmission,improves the transmission capacity of terahertz communication system,which provides a reference for the later design of terahertz communication system,especially indoor terahertz communication system.…”

Application of Reverse Time Migration to Faults Imaging in Rakhine Basin, Myanmar by Seonghyung Jang, Donghoon Lee

“…Although faults are an indicator of possible hydrocarbon traps, they are difficult to identify in seismic images using traditional stack or prestack time migration due to the rather complex behaviors of wave propagation. On the other hand, prestack depth migration (PSDM) can significantly improve the accuracy of seismic images, especially of complex subsurface structures such as faults, folds, overthrusts, and salt domes. …”
