What is it about?
In collaboration with Prof. Isabelle Huynen (UCL), we devised a simple setup to measure directly interactions between a sample in powder form and electromagnetic waves. This gives information about possible applications in metamaterials area.

Why is it important?
Very simple yet reliable method to measure directly on powders, including nanoparticles! It allows to avoid diluting the sample in paraffin or polymer matrix.
Perspectives
This method was used to characterize magnetic nanopowders: magnetite (iron oxide) nanoparticles supported on graphene, see our related publication: "Decoration of nanocarbon solids with magnetite nanoparticles: towards microwave metamaterial absorbers", Francisco Mederos-Henry, Benoit P. Pichon, Yzaora Tchuitio Yagang, Arnaud Delcorte, Christian Bailly, Isabelle Huynen and Sophie Hermans, Journal of Materials Chemistry C, 2016, 4, 3290 - 3303.
