Apologies—I realized I moved on to a follow-up question before properly acknowledging your earlier comment. Thank you — I appreciate...

I’m an electronics engineer trying to understand the physical limits of using free‑electron density to modulate the refractive index of...

Thanks for the detailed calculation — this helps me understand the limits much more clearly. I wasn’t aware that the plasma frequency of...

“I’m considering a fixed‑thickness plasma layer on the order of ~50 µm. The idea is to vary the electron density inside that layer to...

Thanks, this is very helpful. Treating it as a multilayer interference filter with one layer having a tunable dielectric constant is a...

Thanks, Andy — this really helps me understand how to frame the problem. By “thin,” I mean physically thin (micron‑scale or less) and...

I’m trying to understand how to model EM wave propagation through a very thin, low‑density plasma layer (micron‑scale thickness). The...

Andy, thanks again — your explanation helped clarify the connection between plasma permittivity and wave propagation. I have a follow‑up...

Thank you, Andy — this is very helpful. Yes, the structure I’m considering involves a very thin gas layer, so I was hoping the plasma...

Hello everyone, I’m exploring a conceptual question involving the optical behavior of micro‑plasmas in thin, sealed cavities. The idea...

? Hello everyone,My name is Ronald Coleman, and I’m a retired engineer and inventor based in Temescal Valley, California. I spent many...
