Tunable frequency selective surfaces (FSSes) usually have better flexibility and are employed by many applications. However, the frequency tunable range is usually not very broad especially for the band-stop ones. At the same time, a tunable FSS usually requires a bias network, which makes the design even more difficult. In this paper, a broadband tunable(More)
This paper proposes to generate a smart tool that can inherently and effectively capture the results of parameter variations on the system responses of lumped and distributed electrical circuits. This methodology leverages the so-called affine arithmetic and represents parameter-dependent responses in terms of a multivariate polynomial. The affine(More)
