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.
