NRN045 - The generation of triangular meshes for NURBS-enhanced FEM
This paper presents the first method that enables the fully automatic generation of triangular meshes suitable for the so-called non-uniform rational B-spline (NURBS)-enhanced finite element method (NEFEM).
NRN045 - Analysis of the Direct Modulation Response of Nanowire Lasers
The response of nanolasers to direct current modulation has been analyzed in both the small-signal and large-signal regimes. Calculations have been performed using rate equations which include the Purcell cavity-enhanced spontaneous emission factor F and the spontaneous emission coupling factor β. It is observed that in general increased F and β reduce the 3-dB direct current modulation bandwidth. Conditions are identified where the peak modulation response at resonant frequencies 35 and 30 GHz can be achieved. For both small- and large-signal regimes, modulation bandwidth of approximately 55 GHz can be achieved.
NRN045 - Exact 3D boundary representation in finite element analysis based on Cartesian grids independent of the geometry
Wiley Online Library
This paper proposes a novel Immersed Boundary Method where the embedded domain is exactly described by using its Computer-Aided Design (CAD) boundary representation with Non-Uniform Rational B-Splines (NURBS) or T-splines.
NRN024 Subcarrier Index-Power Modulated Optical OFDM
A novel transmission technique known as subcarrier index-power modulated optical orthogonal frequency division multiplexing (SIPM-OOFDM) is proposed
NRN026 - Resonant-state expansion of dispersive open optical systems: Creating gold from sand
In this paper we present a new fundamental method for calculating RSs in open optical systems, generalizing the RSE to treat arbitrary physical materials, by including the frequency dispersion of the permittivity.
