AI Thread Summary
A 10GHz plane wave strikes an 8mm thick slab with a dielectric constant of 2.5, prompting a discussion on the proportion of incident power transmitted through the material. Participants are encouraged to calculate the amplitude of the transmitted wave and the time-averaged Poynting vector to determine the power transmission. The relevance of the topic to electromagnetic theory, specifically E&M 2, is questioned. A helpful resource is provided, linking to the Fresnel Equations for further insights. The discussion aims to clarify the transmission characteristics of electromagnetic waves through dielectric materials.

A plane wave at a freq. of 10Ghz falls normally onto a pane slab of material of thickness 8mm. The dieletric constant of athe material is 2.5. Estimate the proportion of incident power transmitted.

I need a tip
 
Physics news on Phys.org
Is this E&M 2?

Find the amplitude for the transmitted wave and then the time averaged pointing vector for the power transmitted.

Does this help?
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
