The application scenarios and requirements are more diverse in the fifth-generation (5G) era
than before. In order to successfully support the system design and deployment, accurate …

During the railway engineering design, it is difficult to quickly evaluate the influence of the
superstructure architectural structure on the wireless network coverage in the facilities …

In the proposed chapter, the authors present a geometric-statistical propagation model that
defines three groups of received signal components, ie, direct path, delayed scattering, and …

In this paper, radio propagation predictions were performed by a self‐developed ray tracing
simulator based on highly accurate three‐dimensional (3D) environment models obtained …

Radio environment maps (REMs) are beginning to be an integral part of modern mobile
radiocommunication systems and networks, especially for ad-hoc, cognitive, and dynamic …

With the development of the smart railway, new services need to be supported by fifth-
generation (5G) technology. Comparing to 5G technology, 5G-railway (5G-R) is more …

ART-PO algorithm for the estimation of the Radar Cross Section of electrically large targets
coated with radar absorbing materials is presented. The proposed method relies on the …

Numerical evaluation and/or measurement campaigns are currently the only means of
evaluating the isolation between antennas; in the former case, the simulation time and …

A method for a fast prediction of the Radar Cross Section (RCS) reduction of large scattering
objects coated with radar absorbing materials is presented. The proposed technique is …

We describe the contribution of diffractive orbits to semiclassical approximations of Wigner
function propagators. These contributions are based on diffractively scattered rays used in …
