PROPERTIES OF THE BAND GAPS IN 1D TERNARY LOSSY PHOTONIC CRYSTAL CONTAINING DOUBLE-NEGATIVE MATERIALS
Theoretically, the characteristics matrix method is employed to investigate and compare the properties of the band gaps of the one-dimensional ternary and binary lossy photonic crystals which are composed of double-negative and double-positive materials. This study shows that by varying the angle of incidence, the band gaps for TM and TE waves behave differently in both ternary and binary lossy st...

POLARIZATION DIVISION MULTIPLEXING OF OFDM RADIO-OVER-FIBER SIGNALS IN PASSIVE OPTICAL NETWORKS
This paper describes the state-of-the-art of polarization multiplexing for optical networks transmission. The use of polarization division multiplexing (PDM) permits to multiply the user capacity and increase the spectral efficiency. Combining PDM and orthogonal frequency division multiplexed (OFDM) modulation allows maximizing the optical transmission capacity. The experimental demonstration of t...

TOTAL INTERNAL REFLECTION-BASED HIGH EFFICIENCY GRATING DESIGN FOR A METAL-FREE POLARIZING FILTER APPLICATIONS USING HYBRID OPTIMIZATION PROCEDURE
This paper presents a fast and rigorous design method for grating-based metal-free polarizing filter applications using two-step hybrid optimization techniques. Grating structures utilizing the total internal reflection in a lamellar configuration were used to achieve metal-free solution, which is a key technology in the chirped pulse amplification for high power laser system. Here two polarizing ...

ELECTROMAGNETIC IMAGING OF TWO-DIMENSIONAL GEOMETRIES BY MULTIPULSE INTERFERENCE USING THE INVERSE FDTD METHOD
The size, shape, and location of unknown objects in the ground and in the body can be estimated by an electromagnetic imaging technique. An imaging approach to clear detection of two-dimensional geometries is proposed in this paper. Based on the inverse finite-difference time-domain (FDTD) method, a phase interference technique using multidirectional pulses is employed. The advantage of the propos...

OPTICAL RESPONSE TO SUBMICRON DIGITAL ELEMENTS SIMULATED BY FDTD WAVELETS WITH REFRACTIVE IMPULSE
Accurate simulation from digital, submicron, optical elements is obtained by finite difference time domain (FDTD) results that are phase analyzed as sources for Huygens wavelets on fine scales much shorter than the wavelength used. Results, from the MIT electromagnetic evaluation program, are renormalized by a method here called “refractive impulse.” This is valid for polarized responses from ...

LOW-FREQUENCY RAMAN SPECTROSCOPIC MONITORING OF SUPRAMOLECULAR STRUCTURE IN H-BONDED LIQUIDS
Effective density of vibrational states in H-bonded liquids was measured by Raman scatteringmethod. Actuality of a low-frequency part of the spectrum of the intermediate (fracton) region, which obeys a power law, indicates the correct application of the percolation model. The dependence of exponent on binary solutions concentration has been studied. Existence of correlation of the fractal structur...
