Maxwell Stress Tensor

1. Homework Statement
x and y are nonconducting cylindrical shells. Both cylindrical shells are surrounding long wires that are carrying current. the x shell out of the page and the y shell into the page.
x radius has a charge per unit lenght = to +$$\lambda$$
y radius has a charge per unit lenght = to -$$\lambda$$
I need to calculate the maxwell stress tensor at a midway between x and y. (from the picture)

2. Homework Equations

Tij =$$\epsilon$$o(EiEj-$$\delta$$ijE2)+(1/$$\mu$$)(BiBj-$$\delta$$ijB2)

3. The Attempt at a Solution

How do I exactly found the i and j component of the magnetic and electric field?
