Slow wave propagation
WebbStick–slip in sliding of soft adhesive surfaces has long been associated with the propagation of Schallamach waves, a type of slow surface wave. Recently it was demonstrated using in situ experiments that two other kinds of slow waves—separation pulses and slip pulses—also mediate stick–slip (Viswanathan et al., Soft Matter, 2016, … WebbSlow-Wave Propagation Properties of Substrate Integrated Waveguide Based on Anisotropic Artificial Material Abstract: In this paper, an inductor-loaded slow-wave substrate integrated waveguide (SIW) is presented and studied. The proposed structure features a number of unique propagation properties.

Webb3 apr. 2024 · The combination of these processes results in the wave tip of the trailing wave striking the wave back of the lead wave followed by the rapid merging of the wave backs of the two waves. An additional complication is that the back of the lead wave is also slowing down as the wavelength of a lead wave always increases with depth.
