Imagine a MIMO communication system that fully exploits the propagation characteristics offered by an electromagnetic channel and ultimately approaches limits imposed wireless communications. This is concept of Holographic Accurate tractable modeling critical to understanding its full potential. Classical stochastic models used communications theorists are derived under far-field assumption, i....

We demonstrate the existence of surface waves in two-dimensional photonic crystal slab edges. In finite-sized air-terminated photonic crystal boundaries, the slab-edge mode turns into a lasing mode under pulsed optical pumping conditions. Analyses of the modal behaviors of the slab-edge modes by means of calculations based on the plane wave expansion method and the finite-difference time-domain...

This paper deals with the design and simulation of all-optical 4×2 encoderusing the wave interference effect in photonic crystals. By producing 4 opticalwaveguides as input and two waveguides as output, the given structure was designed.The size of the designed structure is 133.9 μm2. The given all-optical encoder has acontrast ratio of 13.2 dB, the response time of 0.45 ...

In this study a wide bend, low loss (>2.0dB) Y-splitter has been designed for TE-polarized light. The structure consists of hexagonal lattice where circular Si-dielectric rods in air background have been organized. For optimal design of photonic band gap, inter-cell distance and cell radius have been varied to find the largest photonic band gap which should corresponds to the optical communicat...

The investigation of teams and teamwork in cooperative (e.g., group brainstorming and team decisionmaking) and mixed-motive (e.g., negotiation) contexts has been carried out through a variety of lenses anddisciplines.One lens that has not beenused to rigorously theorize about andempirically investigate teams is that of ideologies. In this review, we juxtapose the study of a particular status-re...

This paper describes our use of Prolog Word Experts (PWEs) in the Senseval-2 competition. We explain how we specify our PWEs as sequences of transformation rules and how they can be trained on sense tagged corpus data. We give a semantics of PWEs by translating them into first order predicate logic, and we describe how PWEs can be compiled into Prolog procedures. We finally present our results ...

The band structure of two-dimensional chalcogenide glass photonic crystal of triangular lattice structure is calculated at terahertz frequencies using Plane Wave Expansion Method. The band gap ratio was found to vary with variation of the structural parameters such as fill factor and dielectric contrast. The spatial asymmetry associated with lattice structure gives rise to a complete photonic b...
