Based on the vector form intrinsic finite element (VFIFE) method, both the bridge and non-ballasted track are discretized into a set of mass particles connected by massless beam elements, ...

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular ...

Length, width, height measurement example scheme vector illustration. 3D isometric box model block with proportional panes as guide for dimensions. Simple explanation info for metric system accuracy.

In this article, we propose a method based on the aperture antennas theory to understand the limitations of orbital angular momentum (OAM) antennas in far-field links. Additional insight is also given ...

We compare the technique of using the orbital angular momentum (OAM) of radio waves for generating multiple channels in a radio communication scenario with traditional multiple-in-multiple-out (MIMO) ...
