Metamaterial dispersion
First Claim
1. A method comprising:
- identifying a plurality of metamaterial particles, each metamaterial particle interacts with an electric component and a magnetic component of electromagnetic signals to absorb the electromagnetic signals; and
dispensing the plurality of metamaterial particles into a fluid medium in an atmosphere, the plurality of metamaterial particles being mobile within the fluid medium and forming a transient dispersion that absorbs electromagnetic signals in the atmosphere.

Abstract
The present disclosure relates to forming a dispersion of metamaterial particles in an atmosphere. The metamaterial particles can be dispersed into the atmosphere, for example, from an aircraft or another type of platform, to form the dispersion. The resulting dispersion can interact with electromagnetic signals in the atmosphere. The particles may strongly interact with both the magnetic and electric field components of the electromagnetic signals. In some implementations, the dispersion absorbs electromagnetic signals in a frequency range. In some implementations, the dispersion modifies electromagnetic signals in a frequency range, for example, by applying a phase shift, a polarization shift, a frequency shift, or a reflection angle to the electromagnetic signals.
