Graphite sheets may serve as a substitute for carbon-loaded Teflon in millimeter wave dosimeters, as they are semi-conductive and can heat when exposed to electromagnetic radiation. The discussion highlights challenges in sourcing carbon-loaded Teflon, prompting the exploration of alternative materials. Teledeltos Paper, a type of resistive paper with a resistance of 800 Ohms per square, is suggested as a potential option, particularly when layered. The feasibility of using these materials hinges on their ability to replicate the desired heating effect. Overall, the conversation centers on finding effective alternatives for the original experimental setup.

Hi I'm trying to duplicate the experiment in the paper I've attached. I'm having some trouble sourcing the carbon loaded teflon described in the paper. Would something like graphite sheet work? I guess as long as you had something semi-conductive that heats so when EM radiation passes thru it, it should work?

WE have recently been discussing resistive paper on the Forum, maybe it will work, especially two layers of it? It is 800 Ohms per square. It is called Teledeltos Paper and is available from education suppliers.

Thread 'The rocket equation, one more time'

I already posted a similar thread a while ago, but this time I want to focus exclusively on one single point that is still not clear to me. I just came across this problem again in Modern Classical Mechanics by Helliwell and Sahakian. Their setup is exactly identical to the one that Taylor uses in Classical Mechanics: a rocket has mass m and velocity v at time t. At time ##t+\Delta t## it has (according to the textbooks) velocity ##v + \Delta v## and mass ##m+\Delta m##. Why not ##m -...
