In this article we compare two solutions to improve the radiation pattern of a slotted Substrate Integrated Waveguide (SIW) antenna: use of an E-plane array and covering it with a metasurface (MTS).

Slot arrays fed with post-wall waveguides were fabricated using conventional printed circuit substrates. Side-walls of waveguides are emulated using rows of closely spaced vias. These arrays have been ...

We investigate the effect of molecular geometry and conformational flexibility on electronic coupling and charge transfer interactions within propeller-shaped perylene diimide (PDI) tetramer arrays ...

UPS vs NPS calculation: The government has extended the due date for opting between the Unified Pension Scheme and the National Pension System from June 30, 2025, to September 30, 2025. The ...

Highly oriented SiC porous nanowire (NW) arrays on Si substrate have been achieved via in situ carbonizing aligned Si NW arrays standing on Si substrate. The resultant SiC NW arrays inherit the ...
