Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it is predicted that the nonlocal response blueshifts the resonance peak, modifies the electric field ...

Analysis Of The Design Criteria For Ancient Greek And Roman Catapults

K.M. Paasch
Center for Product Development, Mads Clausen Institute, South Danish University, Denmark

This paper will give a short overview of use of COMSOL Multiphysics for analyzing ancient Greek and Roman catapults with the main focus on the energy storing torsion springs. Catapults have been known and used in the Greek and Roman world from around 399 BC and a fully standardized design for powerful torsion catapults emerged around 270 BC, based on one basic factor, the diameter of the torsion ...

In this paper, we use a COMSOL Multiphysics® model to demonstrate the potential use of polymer microring resonator structures for optical biosensing applications. When the refractive index of the area surrounding the microring resonator changes, there is a shift in the resonance wavelength that can be monitored. We present simulated results of the spectral response with different refractive ...
