How Microwave Lenses REALLY Work!

Refraction, Focusing and Magnification are usually explained because light “slows down“ in transparent materials. But DOES it? 3D-printed Microwave Dielectric Lenses are transforming how RF Engineers think about focusing Microwave and mmWave energy. Additive machining has changed the design process forever. As well as being an amazing application of 3D printing, dielectric materials are fascinating in their own right, so the detail at the molecular level is completely general and applies to any material at radio frequencies and into the far infra-red. This video doesn’t use the complex jargon of the original video. The only thing I’ve held back on is the equations and the detail of the quantum-mechanical processes involved, but I’ll probably put that on my second channel @MachiningandMicrowavesPlus along with the piece I was going to include about the weird dielectric behaviour of water with RF fields.
