UCT's Petrarch Specialty chemical line is world renowned for being of the finest quality and employed by scientists working at the cutting edge of electronic engineering research. In a paper published by Fan Zhou et al (Northeastern University) in Optical Express ((2016), 24: 6367) a detailed study was reported into Split ring resonators. Split ring resonator (SRRs) were first proposed as the primary building blocks that mimic the properties of orbiting electrons to produce artificial magnetism.  This group of metamaterials composed of rationally designed sub-wavelength inclusions exhibit exotic and unique electromagnetic responses that cannot be found in nature.They have therefore enabled a broad range of novel applications, such as sub-diffraction imaging, invisibility cloaks negative index metamaterials (NIM) and perfect absorbers. This particular study involved the employment of UCT product poly[(mercaptopropy)methylsiloxane] (PMMS). This siloxane was used in the process to fabricate the soft stamps. The compliance of the PMMS stamp made it easier to form a close and conformal contact with the substrate, which is a very important factor for successful pattern transfer with high fidelity. This group successfully report scalable nanofabrication of U-shaped nanowire resonators (UNWRs) using the high-throughput nanotransfer printing method. By providing ample area for conducting oscillating electric current, UNWRs overcome the saturation of the geometric scaling of the artificial magnetism. The added flexibility in transferring to other substrates makes UNWR a versatile building block for creating functional metamaterials in three dimensions.
