Measuring the Spectra of Metamaterials at an Oblique Incidence

X. Ni[1,2], Z. Liu[1,2], and A.V. Kildishev[1,2]
[1]School of Electrical and Computer Engineering, Purdue University, West Lafayette, Indiana, USA
[2]Birck Nanotechnology Center, Purdue University, West Lafayette, Indiana, USA

The emergence of electromagnetic metamaterials has given rise to a variety of fascinating applications, including the perfect lens and the optical cloaking device. For a long time the study of the properties of metamaterials was limited to normal incidence only. However, it is extremely ... En savoir plus

Heating of thermeolectric Bi-Sb thin film due to THz irradiation absorption

A.Tukmakova¹, A.Asach¹, A.Novotelnova¹, I.Tkhorzhevskiy¹, N.Kablukova¹, P.Demchenko¹, A.Zaitsev¹, M.Khodzitsky¹
¹ITMO University, Saint-Petersburg, Russia

We present the model of THz sensor based on thermoelectric Bi-Sb thin films. The model is based on an electromagnetic heating interface and combines radiofrequency and heat transfer modules. The studied frequency was 0.14 THz, irradiation power 30 mW. Films had a thickness of 150 nm and ... En savoir plus

Microfluidic Separation System for Magnetic Beads

F. Wittbrach, A. Weddemann, A. Auge, and A. Hütten
Department of Physics, Bielefeld University, Germany

It is possible to control the motion of magnetic beads using a combination of hydrodynamic and electromagnetic forces. In this work, we investigate the possibility to manipulate the motion of beads with different magnetic moments in a special microfluidic structure so as to separate ... En savoir plus

Simulating Obscurants Under High Energy Laser Illumination

S. Du[1], A. Strikwerda[2], J. Miragliotta[2]
[1]Winston Churchill High School, USA
[2]Johns Hopkins University Applied Physics Lab, USA

Here we present a simulation for evaluation of novel obscurant candidates under high-energy laser (HEL) illumination. This approach incorporates thermal modeling into obscurant characterization, allowing for evaluation of the temperature increase of the candidate obscurants as well as ... En savoir plus

Multiphysics Modeling of High Power Magnetron

A. Jadhav[1], K. Tuckley[1], H. Dixit[2], J. John[1]
[1]IIT Bombay, India
[2]BITS Pilani, Hyderabad Campus, India

The magnetron is one of the oldest and the most popular of the vacuum tubes. As they are very robust, low cost and highly efficient source of high-power microwaves, they have been a common choice for defence, medical, industrial and commercial applications. This work presents the ... En savoir plus

Studying surface plasmon polariton excitation and field profiles using Wave Optics module in COMSOL®

B. Johns[1], V. Kalathingal[2], J. Mitra[1]
[1]School of Physics, Indian Institute of Science Education and Research, Thiruvananthapuram, India
[2]Department of Chemistry, National University of Singapore, Singapore

Surface plasmon polaritons (SPPs) are coherent oscillations of electrons at a metal-dielectric interface coupled to electromagnetic fields [1]. SPPs offer highly confined fields resulting in larger field amplitude and enhanced light-matter interactions. Control and manipulation ... En savoir plus
