Optical filter is one of the most accurate and important elements in pure optical communication network which uses wavelength division multiplexing (WDM). This research includes studying Acousto Optic Tunable Filter (AOTF) in linear anisotropic medium, which depends on the interaction principle between optical waves and acoustic waves. This paper describes simulating and testing the AOTF in MATLAB/Simulink software which is a strong tool for simulating and designing various systems. We have achieved an AOTF model, and created special block which could be added to MATLAB Simulink Library. We have also evaluated the performance of this filter and its ability to select one wavelength between the set combined by WDM. Moreover, we have studied the effect of acoustic wave frequency, its velocity, the properties of the crystal used in manufacturing it, and other influent parameters, along the selected wavelength.

The acousto-optic filters that depend on the interaction technology between the optical and ultrasonic waves are considered a high- performance filters as they have the largest tuning range compared to other filters types. These filters can be used in optical WDM (Wavelength Division Multiplexing) networks. This work aims to study two types of these filters, one operates according to the non-collinear type of interaction, whereas the other type operates according to the quasicollinear type of interaction, and compare between these two filters types from the practical side. Thus, this work aims to show the tilt angle effect of the acoustic wave on the filter's design and its efficiency in electing the desired optical wave length, in addition to compare the frequency curves related to these angles in terms of their sensitivity to the changes of the incidence angle. The importance of this work lies in proving the efficiency of the filters operating according to the quasi-collinear type of interaction and their ability to achieve the high values of quality factor.
The simplified dynamic mathematical model of hybrid stepper motor was studied in this research. The aim was to simplify the study and to concentrate on certain topic of this subject. The mathematical model which describes their mechanical and elect rical dynamic behavior of the mentioned motor was done. Whereas, the mechanical model can be derived by Newton law, and electrical model can be derived by Kirchhoff law depending on the electrical equivalent circuit to each phase.
This research involves a simulation of four channels coarse wavelength division multiplexing (CWDM) transceiver. The study is done on the effect of the extinction ratio(ER) of the directly modulated laser (DML) diode, the effect of using Erbium doped fiber amplifier (EDFA) in optical fiber links on the quality factor (Q) and the bit error ratio (BER) when using different lengths of fiber. Then a comparison is made between the CWDM network using the amplifier EDFA and the same network without using the amplifier EDFA. In addition, the study is done on the effect of optical fiber length on Q with and without the amplifier EDFA, and we demonstrated the relationship between them diagrammatically.
The objective of this research is to model the dynamic characteristics of lead-acid batteries taking into account their fundamental phenomena (the electric double-layer, the charge transfer and diffusion phenomenon due to oxidation and reduction reactions). The value of the equivalent circuit elements used in modeling is determined experimentally using a pulsed discharge of the battery.
