A new approximate method for predicting the resonant frequencies and for solving the field distribution problem of a cylindrical dielectric resonator (DR) is developed. The model proposed in this paper bridges the gap between rigorous and accurate finite-element or Green function-based numerical methods on the one hand and on the other hand, simple(More)
We present a novel dielectric resonator (DR)-based resonant structure that accommodates aqueous sample capillaries in orientations that are either parallel (i.e., side-access) or perpendicular to the direction of an external (Zeeman) magnetic field, B(0). The resonant structure consists of two commercially available X-band DRs that are separated by a(More)
Optical network architectures with elastic bandwidth provisioning are a very promising approach for next generation optical networks. Such elastic optical networks will enable efficient resource utilization and flexible sub-wavelength and super-channel connection provisioning to support heterogeneous and immense bandwidth demands. In this paper, we focus on(More)
In this paper we address the problem of the impairments in Radio-over-Fiber (RoF) transmission which occur in an optical link in a millimeter-wave (mm-wave) band, e.g. for 60 GHz carrier frequency. We carry out some basic relations between DSB, SSB and OSC modulation formats and than compare duobinary and RZ modulation by numerical simulations.
In this paper we address the problem of the Radio-over-Fiber (RoF) network design. In particular, we focus on a DWDM RoF network for which we formulate a maximal service RoF channel allocation (MSCA) problem. Although MSCA is a difficult problem, still it can be resolved for the network instances of some hundred of access points and users.
We introduce a mixed-integer optimization model for two-layer IP-over-Flexgrid networks, and present a cost study performed using the CPLEX package for the introduced model. The study concerns a generic German network with 12 nodes and 20 links in the optical layer, and a set of six IP traffic matrices with increasing demand volumes. The optimization(More)
Closed-form analytical expressions for nonlinear noise power FWM density (I<sub>FWM</sub>) have been derived for Nyquist WDM systems as a function of the optical fiber and system parameters (i.e. dispersion, nonlinearity, power spectral density, and spectral efficiency) in case of near-zero fiber attenuation.
