Complete parts a and b THe answers should be clear and shoul

Complete parts a and b. THe answers should be clear and should not be too lenghty. Electromagnetics :)

At the boundary between two dielectrics we know the following E_1=Aaphi-Ba theta+Ca_p V/m E2= Aa phi - 4Ba0+Cap V/m What can you say about the boundary looking at the above, what information can you find about the interface between the two regions? If region 2 is air and region 1 is material with relative permittivity of 4 do you think there is a surface charge density at the boundary? If there is provide the value and if there is not explain why. Your answer should be in terms of A, B, C and e_0

Solution

1) A general set of boundary conditions at fluid-permeable interfaces between dissimilar fluid-filled porous matrices is established starting from an extended Hamilton–Rayleigh principle. These conditions do include friction and inertial effects. Once linearized, they encompass boundary conditions relative to volume Darcy–Brinkman and to surface Saffman–Beavers–Joseph dissipation effects.

Yes we can find interface between the two boundary conditions

2) we know the suface charge density

= q/A

where q= charge and A= area
