Repulsive Casimir forces with finite-thickness slabs
Repulsive Casimir forces with finite-thickness slabs
We use the extended Lifshitz theory to study the behaviors of the Casimir forces between finite-thickness effective medium slabs. We first study the interaction between a semi-infinite Drude metal and a finite-thickness magnetic slab with or without substrate. For no substrate, the large distance $d$ dependence of the force is …
