Advanced Theory and Simulations, Volume 6, Issue 12, December 2023., 2023 Approach based on the relationship between the zeros and poles of a discrete linear time‐invariant (LTI) low‐pass filter designed using Butterworth and Chebyshev type I polynomials and the parameters of a leaky‐wave antenna (LWA) array. The method is able to produce a pass‐band without ripple, joint control on the pass‐band and rejection‐band, as well ...

Leaky-Wave antennas with arbitrary radiation based on bianisotropic Huygens’ metasurfaces [PDF]
, 2018 In this contribution, we present the application of Huygens’ metasurfaces (HMS) to the arbitrary design of leaky-wave antennas (LWAs). These metasurfaces have demonstrated their capabiity to tailor the electromagnetic waves at will. We use them to design
