AI Thread Summary
To compute the electric field, polarization, and flux density at the dielectric-conductor interface, apply Maxwell's equations along with the relevant boundary conditions. The discussion highlights the importance of considering both bound surface charge density (sigma b) and free surface charge density (sigma f) in the calculations. The tangential and perpendicular components of the electric field can be determined using these boundary conditions. Additionally, the relationship between the D vectors on either side of the interface is crucial for accurate results. Understanding these principles is essential for applications in capacitors and potentially in surface plasmon resonance contexts.

How do I compute the electric Field, polarization and flux density at the interface of a dielectric material and a conducting Material?
 
Physics news on Phys.org
Use Maxwell's equations with the appropriate boundary conditions. Without any additional information, that is about the best answer I can give.

Is this question in the context of Capacitors, or does it have a connection with Surface Plasmon Resonance?

Claude.
 
Thanks Claude
 
In regards to the conditions of Megans question the question just states that there is a bound surface charge density sigma b, and a free surface charge density sigma f.


So how do I use that in Maxwells equations?
 
You can find the tangential and perpendicular components of the electric field at the boundary using the boundary conditions.

Think about how the D vectors on both sides of the interface are related at the interface.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
