Utilization of monolithic materials with ultra high dielectric constant (&[epsilon] r = 800 -1200) to generate a drastically focused and enhanced transmission field in the sample of interest (up to 500% increased) and reception field (up to 4 fold increased) with standard hardware at 3T. Currently this translates to at least 40 % higher signal to noise ratio with strong potential higher values. Additionally the transmission power was reduced to 1/3 (&[epsilon] r =800) and respectively 1/27 (&[epsilon] r =1200) of the initial power with no uHDC material.
