Novel rejected and passed band devices are obtained using techniques in two dimensional Photonic Band Gap microstrip structures. The microstrip is engraved in a PBG dielectric constituted of a via holes array and enclosed in a metallic box. The boundary element method (BEM) and the fast wave concept iterative process (FWCIP) are combined to evaluate the characteristic of this structure.

Recently PGB (photonic band gap) filters show a great
development. Here we will present two different PGB filters with
lattice etched in the ground plane. The rejection band characteristic
is function of the number and shape of elements etched. Th
ese
filters are modelling by the FWCIP method.
In this paper we will study the usage of equivalent circuit; in
modeling a round shaped metal cylinder in rectangular waveguide
to get filters that can be calibrated and used in the microwave
domain. We will study the structure of a rectangular re
sonant
cavity linked stimulatory through thick openings. Also a metal
shape to be calibrated in rectangular resonant cavity linked
stimulatory through thick openings. We will use matlab for showing
transition and reflection factors for the suggested filters.
In last decade, many of researches have proposed to study materials with periodic
structures,These structures can be engineered to realize novel electromagnetic properties
and to achieve behaviors that are not found in naturally materials. These ma
terials have
negative permittivity and permeability .Those are called meta-material or Left Hand
Material (LHM), They are fabricated, studied and analyzed within different applications of
microwave and optical communication. Recently, the microwave engineering applications
of artificial metamaterials have been widely discussed and various novel microwave
components were achevid for example, filters, antennas and fiber optic. This paper studys
and analyzes the reflection from fractal distribution of MMs layers in RHM medium, using
the recursive method, and applies it in the design of microwave narrow band filters.
This paper presents a three phase shunt Active Power Filter (APF) for power quality
improvements in terms of harmonics compensation. The compensation process is based on
measure non-liner load currents and Active Filter currents, and then extract t
he references
from measured currents. Measured currents are then transferred from abc frame to d-q
reference frame. A Synchronous Proportional Integral controller (Synchronous PI
controller) is used. The control signals then drive the Pulse Width Modulation (PWM)
routine, where its output controls the Voltage Source Inverter (VSI) switching devices. The
performance of the Active Filter and the Synchronous PI controller is validated though the
simulink results in MATLAB environment.
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 mediu
m, 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.
