Intelligent transportation systems (ITSs) of industrial systems have played an important role in Internet of things (IOT). The assistant calibration system (ACS) of vehicles is an emerging technology, which services the driver to drive the vehicle safely. To solve some existing problems in ACS such as frequency pairing, vehicle localization judgment, and(More)
The nth-order PMLs based on the unsplit-field formulations and the Z-transform methods are proposed to truncate the finite-difference time-domain (FDTD) domains, which will be validated through numerical simulations whether the higher-order PML with more than two poles, such as n=3, will hold better absorption performance as compared with the conventional,(More)
A novel implementation of the uniaxial perfectly matched layer (UPML) based on the D-H formulations is presented to truncate the finite-difference time-domain (FDTD) lattices. The method of direct discretizing the second-order differential equation is employed by the proposed algorithm in some PML regions. Two numerical tests have been carried out to(More)
