Parallel-Plate Waveguides Formed by Arbitrary Impedance Sheets [PDF]
arXiv, 2019 In this work, we introduce and study parallel-plate-waveguide structures that are formed by two penetrable metasurfaces having arbitrary sheet impedances. We investigate the guided modes which can propagate in such structures and derive the corresponding dispersion relations.

Low Frequency Noise in Randomly Stimulated Asymmetric Oscillators [PDF]
arXiv, 2018 A new mechanism of low frequency (1/f-like) noise generation is described and analyzed. It is attributed to higher frequency asymmetric resonance modes, which are stimulated by a random factor, e.g. due to thermal excitation. One-dimensional models of bi-harmonic and non-linear asymmetric oscillators are presented to prove the concept, and a method of ...
