In Eq. (1) A is the amplitude, f is the phase, and S is the eikonal. For the special case of harmonic waves the phase f is a sinusoidal function of its argument. The form (1) describes an undistorted propagation of a signal. If A is not constant, then the volume of the signal...

Using the method of time-dependent perturbation theory from quantum mechanics, we expand the probability amplitude in powers of the matrix elements Ck(t)=Ck(0)+Ck(1)+Ck(2)+... and substitute it into the wave amplitude equation to obtain by order Ck(1)=−i∑k′Ck′(0)Ck−k...
Specifically, we have determined that parasitic reflections at the amplitude modulator are responsible for the reduced spectral width. In addition, our model for a two-level system cannot fully capture the whole physics of a semiconductor amplifier, in particular by neglecting the linewidth enhancement...
Physics - Popular PhysicsAn equation, fundamental for solar energy applications, can be used to determine the sunrise amplitude at given latitude. It is therefore suitable for being applied to archaeoastronomical calculations concerning the orientation of towns, worship places and buildings. Here we ...

We observe that the amplitude and shape of the bright-dark lump wave keep unchanged during the propagation. We observe that the amplitude and the shape of the shock wave keep unchanged during the propagation. Besides, we graphically analyze the effects of the constant coefficients in the (3+1...
The numerical simulations of a few solutions that were discovered are provided in this section by selecting appropriate values for arbitrary parameters. The soliton has the ability to keep its amplitude, velocity, and form constant throughout its propagation. These reported solutions have some physical...
For one, separation will be a prominent feature whenever the local effective incidence is large, such as when fast, large amplitude kinematics take place. Solutions to overcome this have been proposed in the literature, such as semi-empirical models for dynamic stall in 2D aerofoil theory [135,...
