Theoretical and experimental study of electromagnetic forces in photonic crystals with defects

In this work we studied the possiblity of increasing electromagnetic forces by adding a lossy defect layer in a microcavity like structure. We have experimentally characterized optical transmission and compare with a theoretical model in this structure. Results showed that we can use gold thickness up to 5 nm to have a good transmision of energy and therefore we should expect the appearence of tangential electromagnetic forces within the structure.
