High-Order Harmonic Radiation of a Single Helium Atom Driven by a Strong Laser Pulse

A. Czirják[1], S. Majorosi[2]
[1]University of Szeged, Hungary
[2]Univesity of Szeged, Hungary

Attosecond light pulses have revolutionized our view of fundamental atomic, molecular and solid state processes in the attosecond - femtosecond time domain [1]. The availability of such pulses is based on high-order harmonic generation (HHG) in noble gas samples by a femtosecond laser ... Per saperne di più

Lightning-Fast Simulation of Open System: an Effortless Modal Approach

P. Chen[1], Y. Sivan[1]
[1]Ben Gurion University, Israel

A key goal of nanoscale quantum optics is enhancing the weak interaction of light with matter, enabling applications such as spectroscopy on individual molecules, generating single photons for quantum computing, solar energy harvesting, passive radiative cooling, and nanoscale optical ...

Design and Optimization of Circularly Polarized Antennas for Mobile Shooting of Sport Events

A. De Vita[1], B. Sacco[1], A. Lucco Castello[1]
[1]RAI - Radiotelevisione italiana, Italy

IntroductionA new circular polarized antenna model for mobile transmission has been implemented in COMSOL Multiphysics® for needs related to shooting sports events on the move. The antenna was required to work in the UHF television frequency band (specifically, 600 MHz) and, if ... Per saperne di più

Traveling-wave Microwave Reactor

A. Martínez González[1], A. Stankiewicz[1], H. Nigar[1]
[1]Delft University of Technology, Netherlands

The significance of electrification of industry increases with the growing influence of renewable electricity as a primary energy source on earth. In this sense, microwave heating is a well-established electricity-based and market-mature technology employed on the commercial scale in ... Per saperne di più

COMSOL Multiphysics® Application to Open Up a New Way of Cooling Superconducting RF Cavities

R. Kostin[1]
[1]Euclid Techlabs, USA

Superconducting RF cavities are broadly employed for charged particle accelerators nowadays and usually cooled down to 2K by liquid helium to become superconducting. A cryoplant with trained personnel is required to provide liquid helium for cooling which makes usage of SRF technology ... Per saperne di più

Dielectric Measurement of a High Permittivity Liquid

D. Karns[1], J. Weatherall[1], Z. Landicini[1], J. Barber[2], B. Smith[2]
[1]Battelle Memorial Institute, USA
[2]U.S. Dept. of Homeland Security, USA

The Electromagnetic Signatures of Explosives Laboratory (EMXLAB) at the U.S. Department of Homeland Security, Science and Technology Directorate's Transportation Security Laboratory (TSL) supports the test and evaluation of millimeter wave imaging systems through the measurement of the ...

Numerical Evaluation on Cutoff Frequency of Twisted Waveguide with Rectangular Cross-section

J. Wang[1]
[1]Keisoku Engineering System Co., Ltd., Japan

Waveguides are widely adopted for propagation of high frequency signals. Due to misalignment of waveguide system, bended or twisted waveguide is demanded for connection between waveguides. Compared with straight waveguides, twisted waveguides have a shift of cutoff frequency ... Per saperne di più

Propagation of Radio Signals Over the Sea Surface

K. Koppenhoefer[1], J. Crompton[1], S. Yushanov[1]
[1]AltaSim Technologies, USA

Propagation of radio signals can be significantly affected by the characteristics of the medium in which they travel such that the properties of the propagation path affect both the level and quality of the received signal as well as the distance over which signals can be reliably ...

Computational Modeling of Nanoparticle Heating for Treatment Planning of Plasmonic Photothermal Therapy in Pancreatic Cancer

S. Manrique-Bedoya[1], C. Moreau[2], S. Patel[2], Y. Feng[1], K. Mayer[1]
[1]University of Texas at San Antonio, USA
[2]UT Health San Antonio, USA

Pancreatic cancer is one of the deadliest cancers, with a 7% survival rate at five years from diagnosis. The limited number of treatment options for patients who are diagnosed with late-stage disease is a major contributor to this problem. Therapeutic modalities such as radiofrequency ...
