Very interesting!

It would be even more appealing if you could show a test case where a high level metric (e.g., wifi download speed) improves with one of your lenses compared to a baseline scenario without lense.

Also, I expect the dielectric properties of the printing material will affect the design.

Which printing material have you tested exactly?

Do you know how much the performance changes when cheaper alternatives is used?

Hi frazar0,

We're excited to receive some Radix resin from Rogers Corporation, which is the current standard for developing RF lenses due to its low dielectric permittivity and low loss tangent coefficient.

We also have a few simulated lenses in CST Studio that we will share with you as soon as possible.

If you don't mind me asking, how much does the resin cost ? Couldn't find cost info on their website.

2000 USD is the cost of the 1 liter bottle

This is a good video from Rogers: https://youtu.be/3YMRfw0uWlw

Noyron would be interesting to model these lenses in:
