Multi-tone EMC testing strategy for RF-devices [PDF]

open access: yes, 2012
In low-cost miniaturized electronic systems, filters are often omitted in front of active non-linear components, potentially resulting in unwanted intermodulation products in the band of operation. Current immunity tests most often use a single-frequency

Realization of dual-band topological states in Su–Schrieffer–Heeger-like photonic crystal slabs

open access: yesResults in Physics, 2023
We design the bilayer mirror-symmetric (I-shaped) photonic crystal slabs supporting dual-band topological edge states simultaneously, which is confirmed by the topological phases and localized field distributions.
