3.5-GHz Static Metasurface
This project was completed with my Liquid Metal Electronics team, replicating a design made by our graduate students: Glan Manio, Saige Dacuycuy, and Matthew Kouchi.
The purpose of this design is to reflect signals operating in 3.5 GHz at an angle calculated by the Generalized Snell’s Law, which allows for anomalous reflection and refraction by manipulating the phases of signals.
Before the fabrication process, this was simulated in Ansys HFSS to observe its expected behavior and to compare it to its real measured data.
The design consisted of a Rogers Duroid 5880 as substrate, a copper ground plate, and Galinstan sprayed over in patches using a mylar film as mask during the spraying process. This was designed to reflect signals at a +28 degree angle.
