Abstract [en]

This paper discusses the design of parallel plate waveguide geodesic nses based on parallel curves enabling low-profile beamformers with a ry wide angular scanning range. The proposed approach provides smooth ns profiles with additional degrees of freedom for the optimization of odesic lenses, enabling Gaussian beam but also shaped patterns. The tational symmetry of the lens results in a shape looking like water op ripples, also known as capillary waves, at the surface of a fluid, nce the water drop lens appellation.
