HighRefractiveIndex Materials for Giant Enhancement of the Transverse MagnetoOptical Kerr Effect The ability of plasmonic structures to confine and enhance light at nanometer length scales has been traditionally exploited to boost the magnetooptical effects in magnetoplasmonic structures. These platforms allows for light control via externally applied magnetic fields, which is of prime importance for sensing, data storage, opticalisolation, and telecommunications applications. However, applications are hindered by the highlevel of ohmic losses associated to metallic and ferromagnetic components. Here, we use a lossless alldielectric platform for giant enhancement of the magnetooptical effects. Our structure consists of a highrefractive index dielectric film on top of a magnetic dielectric substrate. We numerically demonstrate an extraordinarily enhanced transverse magnetooptical Kerr effect due to the Fabryxe2x80x93Perot resonances supported by the highrefractive index slab. Potential applications for sensing and biosensing are also illustrated in this work.

Inversion Algorithm of Fiber Bragg Grating for Nanofluid Flooding Monitoring In the current study, we developed an adaptive algorithm that can predict oil mobilization in a porous medium on the basis of optical data. Associated mechanisms based on tuning the electromagnetic response of magnetic and dielectric nanoparticles are also discussed. This technique is a promising method in rational magnetophoresis toward fluid mobility via fiber Bragg grating (FBG). The obtained wavelength shift due to Fe3O4 injection was 75% higher than that of dielectric materials. This use of FBG magnetooptic sensors could be a remarkable breakthrough for fluidflow tracking in oil reservoirs. Our computational algorithm, based on piecewise linear polynomials, was evaluated with an analytical technique for homogeneous cases and achieved 99.45% accuracy. Theoretical values obtained via coupledmode theory agreed with our FBG experiment data of at a level of 95.23% accuracy.
