Optimized Illumination Directions of Single-Photon Detectors Integrated with Different Plasmonic Structures

M. Csete[1], Á. Sipos[1], A. Szalai[1], G. Szabó[1]
[1]Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary

The optimal orientations of different single-photon detector designs were determined by COMSOL software package. Absorption of niobium-nitride (NbN) stripes in two different (p=220 nm, 3p=660 nm) periodic patterns integrated with plasmonic elements was studied. In OC-SNSPDs consisting ... 詳細を見る

Modeling Microwave Waveguide Components: The Tuned Stub

R.W. Pryor[1]
[1]Pryor Knowledge Systems, Bloomfield Hills, MI, USA

The waveguide device modeled here specifically demonstrates the exploration of a small, but very important, subset of components of the family of microwave hardware devices designed to facilitate the optimized transfer of power from the generating source to the consuming load. Each of ... 詳細を見る

Passive Microsensor Based on LC Resonators for Substance Identification

D.A. Sanz Becerra[1], E.A. Unigarro Calpa[1], J. Osma[1], F. Segura[1]
[1]Universidad de los Andes, Bogotá, Colombia

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... 詳細を見る

Determination of the Optical Properties of Individual Gold Nanorods through Numerical Modeling and Experiment

Y. Davletshin[1], J.C. Kumaradas[1]
[1]Ryerson University, Toronto, ON, Canada

The optical scattering and absorption of gold nanorods (GNRs) depends on its size, shape, and surroundings. This dependence is due to both intrinsic and extrinsic effects. A good understanding of this dependence is needed for applications of GNRs in photo-thermal therapy, optical and ... 詳細を見る

Thermo-Elastic Response of Cutaneous and Subcutaneous Tissues to Noninvasive Radiofrequency Heating

J. Jimenez-Lozano[1], P. Vacas-Jacques[1], W. Franco[1]
[1]Massachusetts General Hospital and Harvard Medical School, Boston, MA, USA

Radiofrequency (RF) technology offers unique advantages for noninvasive selective heating of relatively large volumes of tissue. In this work, we present a mathematical model for selective non-invasive, non-ablative RF heating of cutaneous and subcutaneous tissue (with detailed fiber ... 詳細を見る

[1]Prairie View A&M University, Prairie View, TX, USA

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. ... 詳細を見る

EM Simulation of a Low-Pass Filter Based on a Microstrip Defected Ground Structure

J.E. Rayas-Sánchez[1], J. Aguilar-Torrentera[1], Z. Brito-Brito[1], J.C. Cervantes-González[2], C.A. López[2]
[1]Universidad Jesuita de Guadalajara, Tlaquepaque, Jalisco, Mexico
[2]Intel Guadalajara Design Center, Tlaquepaque, Jalisco, Mexico

We perform EM simulations of a low-pass microstrip filter consisting of a cross-junction open stub and two unit sections implemented as defected ground structures (DGS). The defect introduced by unit sections corresponds to an etched lattice on the copper backside ground plane. The ... 詳細を見る

Chiral surface plasmon polaritons on metallic nanowires

S. Zhang
Institute of Physics CAS
Beijing
China

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate. 詳細を見る

Study of Subwavelength Gratings to Understand Their Polarization Behaviour

M. G. Sridharan[1], A. Prabhakar[2], and S. Bhattacharya[2]
[1]Photonics Group, Department of Electrical Engineering, Indian Institute of Technology Madras, Chennai, India
[2]Department of Electrical Engineering, Indian Institute of Technology Madras, Chennai, India

Phase gratings are used in many applications owing to their high transmission and thus higher diffraction efficiencies. COMSOL is based on finite element modeling and is chosen for 2 reasons; firstly, because it can handle complex 2-D and 3-D geometries and secondly, it can handle the ... 詳細を見る
