Abstract:
Recent investigations of dust-density waves in a dusty plasma under microgravity conditions [K. O. Menzel et al., Phys. Rev. Lett. 104, 235002 (2010)] showed that the wave field consists of distinct regions of different frequencies. These so-called frequency clusters are known from simulations of chains of mutually coupled van der Pol oscillators. The behavior of distinct oscillators adjacent to the cluster boundaries were studied numerically. The interaction of these oscillators leads to periodic frequency pulling, a typical feature of driven van der Pol oscillators that is also observed in our experiments.

Electromagnetic Waves in Matter
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore, the...
