Numerical Modeling of a MEMS Sensor with Planar Coil for Magnetic Flux Density Measurements

J. Golebiowski[1], S. Milcarz[1]
[1] Department of Semiconductor and Optoelectronics Devices, Technical University of Lodz, Lodz, Poland

The silicon cantilever with the planar coil was applied to the magnetic flux density measurements. The influence of shape and dimensions of planar coil on magnetic energy density was described. In cause of magnetic anisotropy of analyzed silicon structure FEM method and couple field ... En savoir plus

Photonic Crystal Fibers for Visible Light Generation

D. Aydin [1], S. J. Cordette [1], C. Brès [1],
[1] EPFL, Lausanne, Vaud, Switzerland

There has been a growing interest in optical parametric amplifiers (OPA) for light generation and amplification in because of the possibility for arbitrary operation wavelength and wideband tenability [1]. PCFs are of particular interest in such nonlinear optics applications because of ... En savoir plus

Implementation of a Paraxial Optical Propagation Method for Large Photonic Devices

J.E. Toney[1]

[1]Pennsylvania State University Electro-Optics Center, Freeport, Pennsylvania, USA

We demonstrate the use of COMSOL Multiphysics with MATLAB to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and ... En savoir plus

[2]Center for Metamaterials and Integrated Plasmonics, Pratt School of Engineering, Duke University, Durham, NC, USA

Linear wave propagation through inhomogeneous structures of size R?? (Fig.1) is a computationally challenging problem, in particular when using finite element methods, due to the steep increase of the number of degrees of freedom as a function of R/?. Fortunately, when the geometry of ... En savoir plus

A Broadband THz Cutline Metamaterial Absorber

P. Deshmukh [1], B. R. Sangala [1], G. Rana [2], S. S. Prabhu [1],
[1] Tata Institute of Fundamental Research, Mumbai,India
[2] Indian Institute of Technology Bombay, Mumbai, India

We demonstrate a broadband metamaterial (MM) absorber for THz frequencies. The MM was characterized in the spectral region of 0.3 - 3 THz with THz Time domain spectroscopy (TDS) using 1 mm ZnTe crystal for Electro-optic detection. A strong broadband resonance is observed, centered around ... En savoir plus
