With a growing commercial and innovation potential for software developers to provide new and innovative 5G-empowered network applications (NetApps) across multiple industry verticals, 5G architecture and infrastructure are challenged to continuously evolve in order to cope with all these NetApps requirements. The paper is focused on 5G architectures adaptation for future NetApps and verticals and begins with a short introduction on 5G current and future environment, then continues with the 5G-PPP projects that contributed to early deployment of 5G testbed in Romania. Further we will focus on the NetApps and vertical context, as they are highlighted through the two 5G-PPP projects, VITAL-5G and 5GASP, the step by step 5G network evolution to support all these challenging NetApps and vertical's use cases.
The paper presents an application of the Wave Concept Iterative Process (WCIP) in the case of the study of the scattering of an electromagnetic plane wave by two metallic 2D obstacles. The application is made in order to validate the original method for two classical metallic obstacles diffraction. The case of an infinite circular cylinder is treated first. Modal and iterative convergences are studied. Current density is calculated and compared with the exact solution available for this particular case. The second studied obstacle is an infinite square section scattering obstacle. The 4 faces of the structure are studied independently, mutual influence being not taken into account. Current density results are presented and compared with those issued by the use of other scattering methods for several particular cases
Abstract-The Wave Iterative Process is applied and validated for the study of the scattering of a plane wave by a multiple metallic dipole diffraction structure. The case of a single metallic dipole is treated, at first in normal incidence, than arbitrarily placed with respect to the incident wave. A double dipole scattering structure is studied, mutual influence being taken into account. The diffraction system is further enlarged to 5 randomly placed dipoles, the results issued from the WIP study being compared with those given by the Moments Method. Finally, the possibility of taking into account a very large number of dipoles is examined, by introducing an equivalent dipole distribution. The influence of this approximation on the WIP precision is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
