## Main Question or Discussion Point

Dear Frnds,

my problem is very simple. please help me.

I have a dielectric tensor like:

epsilon_T=

|1 0 0|

|0 1 0| %% note that it is in cartesian co-ordinate system

|0 0 a|

now the potential equation of dipole should be as in spherical system

V=1/(4*pi*epsilon_T (?) *epsilon_0)*(qdcos(theta)/R)

now should i change the epsilon_T value cartesian to spherical system ?

or how i can write down the code ?

should it be V_xx, V_yy and V_zz?

please hurry.
