3D-printed optical devices with refractive index control for microwave applications
- Abstract:
- We present the design, simulation, fused deposition modelling (FDM) 3D printing and characterisation of several structures with spatial variations in refractive index. The 3D-printed structures represent optical devices such as a gradient refractive index (GRIN) lens, a quarter-wave plate, band-absorbers and a GRIN spiral phase plate, all designed to operate in the 12-18 GHz frequency range. The devices were fabricated by using two printheads and bespoke filaments with 'high' and 'low' dielectric permittivity to provide high contrast (up to An = 2) in refractive index thus allowing structures with reduced size. The manufactured devices showed a good agreement with simulation and theoretically predicted performance.
