“Mohamed and Donato developed a truly beautiful method and apparatus to tune dressed cavities,” said Aaron Sauers, the lab’s patent and licensing executive. “I was excited to file the patent application on their invention.”

Hassan and Passarelli see automated balloon tuning as a possibility, which could make it as convenient to use as the current method is for unjacketed cavities. The technique may also find applications in other fields that use similar cavities.

“The hope is that people looking at this idea will get inspired and either adapt or use this technique in their own application,” Passarelli said.
