نعمل في هذا البحث على استخدام الدارة المكافئة في نمذجة اسطوانة معدنية ذات مقطع دائري ضمن دليل موجة مستطيل للحصول على مرشحات يمكن معايرتها و تعمل في مجال الأمواج الميكروية. سنستخدم جسم المعايرة لمعايرة تردد الطنين ضمن دليل موجة مستطيل. نعتمد على إدخال جسم معدني للمعايرة في جوف طنيني مستطيل مقرون تحريضياً من خلال فتحات سميكة. نستخدم بيئة الماتلاب من أجل إظهار معاملات الانتقال و الانعكاس للمرشحات المقترحة.
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 resonant 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.

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
b
oundary 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 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.
The increasingly growth of population led to an increase in the number of
different industrial plants and to arise in their productive capacity which led
to the formation of large quantities of waste products in their gas, liquid and
solid forms.
These waste products led , in turn , to pollute the air , water and soil. This pollution
endangers the whole environment.
In this paper we studied one of the aspects of waterpollution used in chemical
fertilizers factories and the ways of treatment stations designing and the great
role played by these stations in diminishing the great damage caused to rivers ,
lakes , seas and water –store. This has positively a good effect on environment
and economy in general.
It is necessary to operate the used-water treatment stations and recycling this
water after purifying and refining it within the closed-circuit system effectively
and by using modern computerized techniques concerning design , operation and
investment.
This study is of four chapters and a list of references.
The first chapter includes a short glimpse about the treatment stations and their
main lines concerning design and distribution.
The second chapter is about the sections of the phosphate fertilizers factories and
about the acidic water resulting from these sections.
The third chapter gives a glimpse about the treatment of polluted water in the
phosphate fertilizers factory.
The fourth chapter includes the practical section with some designs and results.
Finally , a list of the arabic and foreign references.
This work presents the details of the construction of the temperature
control system in the center. We used the Atmega8 microcontroller
which has high performance speed and suitable memory.
