We present a white-light spectral interferometric technique for measuring the absolute optical path difference (OPD) between beams in slightly dispersive Michelson interferometer with thin-film structure as mirror. record two interferograms to obtain interference signal and retrieve from it phase, which includes effect of cube beam splitter phase change on reflection structure. Knowing effective thickness dispersion made BK7 glass, we use simple procedure determine both OPD. The OPD is...

We developed the thin film microwave magnetic material, M-type barium hexagonal ferrite (BaM) doped with Al, for signal processing devices operating above 40 GHz little to no applied field. Al was chosen as dopant material because it significantly increases already strong anisotropy field of BaM. A series BaAlxFe12-xO19 samples, x ranging from 0 2 in 0.25 steps, were deposited on Pt templates using a metal-organic decomposition growth technique. The resulting films are polycrystalline and...

Surface plasmon resonance has become a widely accepted optical technique for studying biological and chemical interactions. Among others, detecting small changes in analyte concentration complex solutions remains challenging, e.g., because of the need distinguishing interaction interest from other effects. In our model study, resolution ability plasmonic sensing element was enhanced by two ways. Besides an implementation metal-insulator-metal (MIM) nanostructure, we suggest concatenation...
