# Shielding Factor of a Sphere with Finite Conductivity

Calculate the shielding factor of a hollow sphere with finite conductivity. The sphere is constructed from a lossy metal with a thickness of 2.5 nm.

An incident plane wave is defined from 1 MHz to 100 MHz. Use a single near field point located at the centre of the sphere to compute the shielding factor.
