  11. Summary conclusions / recommendations A closer cooperation between the demonstrator part on medical imaging and the theoretical simulations is recommended.

(Thomas, Maria, Soukoulis) Clarify the effect of the small gap (capacitor) in split ring resonators compared to closed ring used in current numerical simulations. (Thomas, ENE. CMS) The issue of absorption by the substrate and the metals (different type) should be addressed. What is the contribution of free carriers in the 10, 35 100 GHz range ?

(Thomas, Maria, CMS) Develop further the new ideas towards applications while considering what is experimentally feasible. (Mike, Ekmel, ENE. CMS) Clarify resolution of swiss rolls in MRI machine together with theory. (Mike) The work on the tapered solenoid concentrator looks like a promising application and should be continued. (Mike)
