WHITTOW, W.G. ... et al., 2009. Reflection and transmission coefficients of nano-metamaterial antennas at microwave frequencies.

The hypothesis of this paper is that when metallic nanoparticles are grouped together by suitable field coupling
they can behave like larger objects which will resonate at microwave frequencies. This means that sheets of nanomaterials
can be designed that are largely transparent at these spectra except where an antenna has been created
from densely grouped clusters of metallic nanoparticles. Simulations, based on actual samples composed of
nano-metamaterials, show the behaviour of the reflection and transmission coefficients of antennas. The resonant
frequency can increase or decrease depending on the geometry.
