Advanced Materials Interfaces, EarlyView.As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

Periodic crack-model of comb transducers: excitation of interface waves
Archives of Acoustics, 2000 A model for a comb transducer is proposed and analyzed. It is shown that interface waves are generated in the comb-sample contact area. The interface waves are leaky waves that transport acoustic energy along the interface towards the comb edges, where ...
