In this paper, the gap waveguide technology is examined for packaging liquid crystal (LC) in tunable microwave devices. For this purpose, a line based passive phase shifter is designed and implemented in a ridge gap waveguide (RGW) topology and fille

In this work, the feasibility of microwave liquid crystal based dielectric waveguide phased shifters is investigated in a phased rod antenna array for the first time. For this, a 1×4 rod antenna array is designed including the phase shifters as well

In this paper, we study the question of whether on smooth projective surfaces the denominators in the volumes of big line bundles are bounded. In particular, we investigate how this condition is related to bounded negativity (i.e., the boundedness of

This letter presents a fully dielectric beam-steering lateral antenna operating at the V-band (50 GHZ). The antenna consists of a semicircular Rexolite body with an embedded liquid crystal (LC) cavity. An electrode network is used in order to align t
