LLeopold89 reacted to fresh_42's post in the thread B What limits a rocket's max speed if in space drag is zero? with
Like.
The amount of energy you can load. And in case you have to protect lifeforms on board, the type and mass of the rocket and therefore... -
LLeopold89 reacted to berkeman's post in the thread B What limits a rocket's max speed if in space drag is zero? with Like.
Yes, it keeps accelerating, but its speed will asymptotically approach the speed of light in a vacuum ("c"). This is described by...

LLeopold89 reacted to DaveE's post in the thread I Resonant cavity with non-resonant dielectric with Like.
There should be lots of stuff on the web. This sounds similar to a stepped index fiber. I found some potentially good stuff just...

LLeopold89 replied to the thread I Resonant cavity with non-resonant dielectric.The paper is exactly what I asked for, thank you. Especially equation 22 $$E_z=C_m I_m(\alpha \rho)F_m$$ for dielectric tubes should be...

LLeopold89 replied to the thread I Resonant cavity with non-resonant dielectric.Yes, I am talking about modes. Resonance comes from my cylindrical cavity. So I have a closed cylinder filled with one dielectric...

LDear Forum, I would like to ask, if a certain construction is possible: I have something like coaxial cable, but instead of a conductor...
