Method of modulation of a wave at very high frequencyJUILLERAT R ZWOBADA ET RJUILLERAT R. ZWOBADA ET R.
The wave height measured behind the bank oscillates in response of the tidal variations (i.e. higher waves coincide with high water). Therefore, the bank acts as a natural offshore breakwater, protecting the beaches behind it. Man-made activities such as dredging could have an impact on the...
When a plane finite‐amplitude wave of frequency f 1 interacts with a plane small‐signal wave of higher frequency f 2, side‐bands at frequencies f 2±nf 1 are produced while the amplitude of the f 2 signal is reduced. Two models have been used to predict the spectrum. The first is ...

Our main finding is that a one to two orders of magnitude change in spontaneous emission time occurs due to two distinct mechanisms: (A) Change in wave function symmetry, where within the direct bandgap regime, strain changes the symmetry of wave functions, which in turn leads to a large ...
structure, and indicates narrow phonon stop bands in the frequency range of interest. As the acoustic wave propagates through the QCL, it perturbs the electrical transport and modulates the THz emission. Although the acoustic pulse has a duration of ~20 ps, the duration of the acoustically ...
