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.

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.
In this Thesis, we have studied, designed and implemented
an energy and economic efficient smart plug system and achieves
high rates of performance. 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.
