Universal Electromagnetic Waves in Dielectric

Tarasov, Vasily E.

Understand

The dielectric susceptibility of a wide class of dielectric materials follows, over extended frequency ranges, a fractional power-law frequency dependence that is called the "universal" response.

  • The electromagnetic fields in such dielectric media are described by fractional differential equations with time derivatives of non-integer order.
  • An exact solution of the fractional equations for a magnetic field is derived.
  • The electromagnetic fields in the dielectric materials demonstrate fractional damping.
