How a material interacts with radio frequency (RF) electromagnetic radiation greatly dictates its potential uses and applications. For some, the purpose of a device is to shield against specific RF frequencies. Other designers are trying to minimize electromagnetic interactions to help preserve signal clarity. In summary, Liquidmetal alloy is more transparent to RF signals than many materials of similar strength and hardness. Put another way, it is much more electromagnetically similar to titanium than to either copper or steel.
This paper breaks down how Liquidmetal compares to other similar and non-similar materials in regards to RF transparency.
