This research illustrates the design of a parallel plate reflector operating in the visible and near infrared fields, with a reflection and/or transmission coefficients equal to 50%, and robust to the polarization of the used light and its extinction ratio (PER), in each of the two directions of polarization (perpendicular S and parallel P). Also there is no need for accurate adjustment of the plate so that the angle of incidence is exactly equal to 45. The research has its various applications in optical measurements laboratories, laser technology laboratories, optical communication laboratories, and photography. One of the most important applications of this plate is ophthalmology devices, which can be used as glasses for people with impaired vision, light measurements in laser laboratories and optical measurements.

Research summary
تهدف هذه الدراسة إلى تصميم وتنفيذ لوحة شبه عاكسة تعمل في مجالات الضوء المرئي والأشعة تحت الحمراء القريبة، مع معامل انعكاس ثابت بغض النظر عن طول موجة الضوء وزاوية السقوط. تم تصميم اللوحة بحيث تعكس 50% من الضوء الساقط وتنقل 50% منه، دون الحاجة لضبط دقيق لزاوية السقوط لتكون 45 درجة. تشمل التطبيقات الرئيسية لهذه اللوحة في مختبرات القياسات البصرية، مختبرات تكنولوجيا الليزر، مختبرات الاتصالات البصرية، والتصوير الفوتوغرافي. كما يمكن استخدامها في أجهزة طب العيون كنظارات للأشخاص ذوي الرؤية الضعيفة. تم تصنيع اللوحة باستخدام زجاج BK7 المطلي بطبقات مضادة للانعكاس وطبقات كروم عاكسة بنسبة 100%، وتم اختبارها باستخدام ليزرات مستمرة بأطوال موجية مختلفة وأجهزة قياس طاقة عالية الدقة. أظهرت النتائج أن اللوحة تحافظ على نسبة انعكاس ونقل ثابتة بغض النظر عن زاوية السقوط، مما يجعلها مفيدة في التطبيقات التي تتطلب دقة عالية في القياسات البصرية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة إضافة قيمة لمجال البصريات وتكنولوجيا الليزر، حيث تقدم حلاً لمشكلة شائعة تتعلق بتغير معامل الانعكاس والنقل مع تغير زاوية السقوط وطول موجة الضوء. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة. أولاً، لم تتناول الدراسة بشكل كافٍ تأثير العوامل البيئية مثل درجة الحرارة والرطوبة على أداء اللوحة. ثانياً، كان من الممكن تقديم مقارنة أكثر تفصيلاً مع التقنيات التقليدية لتوضيح الفروق بشكل أوضح. وأخيراً، قد يكون من المفيد توسيع نطاق التطبيقات المحتملة للوحة لتشمل مجالات أخرى مثل الاتصالات الضوئية المتقدمة والطب الحيوي.

In this research we present results of the studying and calculating the optically active range depth for diffuse light reflected coating at change of the dispersiveness of pigment grains used in coating and wavelength of incident electromagnetic ra diation. This coating consists of zinc oxide powder and organic material that acts as a binding film. The size of zinc oxide powder grains were changed between 0.2 μm and 10 μm. In addition, the depths of optically active range of diffuse light reflected coating were calculated when the absorption coefficient of the pigment used in the ZnO/binder coating changed between -1 0.1cm and -1 1000cm . The obtained results allow us optimization of the diffuse light reflecting coatings thickness at preparation determined kinds of them.
Antennas have become an indispensable basic need, especially in the area of wireless networks, and have developed in the past few decades in a very large way in terms of profit and resistance, bandwidth, bandwidth, radiation pattern, etc. in line w ith new and increasing requirements. In this study, we are interested in studying a broad band antenna where this antenna is very important in systems that operate on a set of frequencies rather than at a fixed frequency. The traditional antennas that are designed at a specific frequency change their response significantly if used on a wide bandwidth around the designed frequency In this study, the LPDA (Log periodic dipole Array) antenna was designed and studied in a broadband field and compared to the antenna reference of wire antennas. It is a halfwavelength antenna λ/2. The study of the effect of frequency change in the antenna radiation pattern and the radiation beam Half-power level and front-to-back ratio (F/B).
The article aims to study the effect of layer thickness and reflection coefficient variation on the image of synthetic seismogram, which is generated by using Ricker Wavelet with wide range of frequencies (20-130Hz) and Vibrator Sweeps with many freq uencies ranges (5-170Hz) as a known technique in reflection seismic method on land. The Researcher tried to determine the relationship between signals recording times and reflection coefficients variation from first side, and recording times with layer thickness variation from second side. The result which is observed that; the recorded times increased proportionally with increasing of the layer thickness (as we know), but it is delayed with exponential relation when the velocity and density are varied within the same layer. New manner is applied to represent the result by using the conversion of time seismic section to raster images by using GIS, this way gave us ability to control the colored scale which reflects the amplitude of recorded signals, and follows the reflectors or get important information about signals amplitude even though the layer thickness is decreased less than wavelet length ten times if we used Ricker signal or Vibration Sweeps.

At the beginning, a comprehensive reference studying the Smart Plug devices. The Smart Plug device was studied, designed and implemented using, which Turn-Off electrical loads in Standby mode to minimize power consumption. The status of all devices connected to the smart plug is shown on the computer display using smart monitor application. The design and implementation of Smart Plug system has saved 1.3% of the total energy consumed in the home per month while achieving economic feasibility and improving the cost of the economic return of the total consumers about 0.7% through the use of the smart plug that has been implemented.
Summary of the thesis In this research, the work examined the role that lasers play in unguided systems in underwater wireless systems (FSOUW), which determine the practical choice of laser system components in unguided systems, and examine the impa ct of the absorption of sea and ocean water to lasers and their association with laser wavelength. Three wavelengths (445, 532, 650) nm have been used to assess the validity of the selection of the appropriate water channel with 100 ml watts of laser as its transmitter energy. SNR, BER and SER were examined following five different water channels. These are pure tap water, and with salt, various concentrations of Malox (MG(OH)2 and Al (OH)3) and salt have been added in order to get high-turbid water, and the results show that mallox and salt content reduces the energy receiving the laser signal and causes disconnection. The charts on wavelength change were drawn with their absorption coefficient in the laboratory for several wavelengths and several types of ocean water and the results were discussed.
