Their innovation lies in a coaxial drone design—a sleek cylindrical form powered by counter-rotating rotors. It’s a departure from the typical quadcopter, offering advantages in performance ...

Abstract: A wideband, reduced loss, and high figure-of-merit (FOM) substrate integrated waveguide (SIW), termed corrugated SIW (CSIW) is introduced in this paper along with the transition for this 2D ...

Abstract: This paper analyses electromagnetic (EM) wave propagation within a metasurface-cladded waveguide filled with magnetized plasma. First, an analytical model is developed to understand the ...

Horn antennas are a fairly simple affair, structurally speaking, with a straight-sided horn-shaped “cone” and a receptacle for standardized waveguide or with an appropriate feed, coaxial adapters.
