Top view of electric field density distribution (a), magnetic field density distribution (b), power loss (c) and sectional view of electric field density distribution (d) in the periodic structure of two split-rings combined with an Al disk at different resonance absorption frequencies. The periodic structure has a thickness of 10 nm. The two split-rings have a ring width of 2 μm, an opening width of 2 μm and an outer radius of 17 μm and 14 μm, respectively. The Al disk has a radius of 9 μm
