Amazing! Readme looks quite well. Not a diving guy TBH , but im sure people into that will find it quite useful.

Luneforge is built on top of Pymesh docker image (a fast C++ Python wrapped Geometry Processing Library)

https://github.com/PyMesh/PyMesh

It requires docker cause its the best way to have all the required dependancies for Pymesh

Conventional PLA. Since its the cheapest and surprisingly extremley stable for Ghz range RF applications

I recommed you to read the research paper "Measuring the Electrical Properties of 3D Printed Plastics in the W-Band "

(https://scholarworks.uark.edu/cgi/viewcontent.cgi?article=10...)

It was really useful for us when developing our lens with an FDM printer. Be warn that it does require an infill of 100% , so it will be quite heavy.

hi!

yes. As a matter of fact while developing this tool as my capstone project at the National Tecnological University here in Buenos Aires , im also planning on developing a 2.4Ghz lens to showcase the capabilities of the project.

2.4Ghz lenses are around 14cm diameter

Luneburg lenses for RF are 100% dielectric.

Luneburg lenses for RF are 100% dielectric.

You print your lens with a known dielectric constant uv curable resin and it its good to go!

Methods like this are the ones that Lunewave (https://lunewave.com/) use for developing RF lenses for their ADAS system

Hi ChuckMcM!

If you are interested , i also developed last year a PLA Luneburg lens for Band X (8Ghz to 12Ghz) using a conventional FDM printer.

We obtained a 6dbm gain @10Ghz

Hi mNovak!

You are 100% right on that. Im working on deploying a free version to access it online so people can check it out.

Also im working on making a step by step guide so people can install it with docker and looking to other alternative ways to installing it locally

2000 USD is the cost of the 1 liter bottle

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.

Thanks for the feedback!

Will try to improve on that , first time on hackernews and first time developing a real open source project

Hi mikewarot,

As a general rule, Luneburg lenses need to have a diameter at least equal to the wavelength of the frequency they are designed to operate with. Because of this, Luneburg lenses are more cost-effective at higher frequencies, making them particularly suitable for applications in the GHz range.

It is possible to develop a Luneburg lens for LoRaWAN, and I am currently working on a DRC check for various wavelengths

Hi! Sorry something might have gone wrong and forgot to add it to the repo.

Its a standard MIT Licence
