I was much impressed by the coverage of the views and the meeting has been extremely useful. I would like to offer the following detailed comment under the heading Electronics page 14.

The electromagnetics of Metamaterials is creating a lot of interest at present because of the potential applications in microwave and millimetre devices. Metamaterials emulate the selective frequency behaviour of crystaline materials by inserting metallic inclusions in conventional dielectric materials. However the electrical size of the inclusions is too large for many applications and there is scope for nanomaterial research here to create size reduced artificial crystaline structures at microwave frequencies.
