Nano-Litz

Litz wire is used to combat high-frequency skin effect loss in solid wires, but conventional wire is not useful above ~10 MHz. A2P Nano-litz developed novel methods to fabricate and manipulate insulated wires ~1um in diameter, enabling fabrication of litz wire optimized for GHz frequencies. We show that our Litz wires have lower loss than solid wires or simple bundles, in agreement with analytical models of litz behavior. This work has the potential for >10x lower resistive losses for many high frequency resonators and inductors, such as probe coils used in nuclear magnetic resonance spectroscopy. This research also highlights work done to demonstrate potential avenues for scaling to commercialization of this technology.
