From: Microwave analogy of Förster resonance energy transfer and effect of finite antenna length

Experimental validation of the antenna length influence on the energy transfer enhancement near a PEC mirror. (a)–(c) are for parallel dipoles and (d)–(f) for perpendicular dipoles, as pictured in the top schematics. Blue triangles are experimental results, orange curves are the result of our analytical model and the dotted black curves are predictions from Green’s function theory. The antenna length normalized by the wavelength L/λ varies for each line, as indicated on the graph, and the separation is kept constant to the antenna length R = L. The root mean square errors σ between the experimental results and the Green’s theory predictions are shown in each graph.
