AI Thread Summary
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 Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (First part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8 and stuck at some statements. It's little bit confused. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. Solution : The surface bound charge on the ##xy## plane is of opposite sign to ##q##, so the force will be...
