The photonic periodic structure was considered as cross shaped, placed on the ground plane. The simulation results from HFSS Ansoft design showed that surface waves can be suppressed by the periodic structure due to the influence of its forbidden band. As a result, the bandwidth of the proposed antenna was 6.7% higher than the conventional antenna. Moreover, the values of gain and directivity of antenna were more by adding PBG in comparison with the values of the antenna alone.

Proposed driver built on a Spartan3 FPGA (XC3S400 core) development board from Xilinx. Implementation of driver realized by an FPGA and using Verilog hardware description language in the Xilinx ISE environment. The driver's control behavior can be adapted just by altering Verilog scripts. In addition, a linear motion system developed (with 4 mm movement per motor revolution) and coupled it to the stepper motor. The performance of the driver is tested by measuring the distance traveled on linear motion system. The experimental results verified using hardware-in-loop Matlab and Xilinx cosimulation method. This driver accomplishes a firm and accurate control and is responsive.

Also, in nonlinear systems, which there are plenty of parameters to be identified and controlled, the fuzzy controllers, will permit more robust control than classic controllers and give stable outputs when exposed to high deviations in the input parameters. Therefore, we used FPGA to solve this issue. This work shows the design methodology of a UAV controller using FPGA which execute fuzzy logic. Appropriate UAV's position, speed and altitude parameters control are essential parts of this study. The proposed fuzzy controller offers performance of 2GFLIPS with 125 MHz FPGA clock. However, with respect to the low usage of the resources on the FPGA, parallel pipelined design of the FLC and the fact that HDL code could be instantiated in parallel, upper calculation power up to about 8GFLIPS is reachable.

In the proposed model, we have used the appropriate method of edge extraction (such as: applying Laplace and Soble mathematical models), where each part is separated and detected, then applying ANN, it is identified for further steps. The paper emphasizes the implementation of the proposed model considering, both "parts images" and "accurate" identifying of finished product parts crossing the line towards ware house or storage using ANN and image processing systems. The most important aim of the paper that we have been seeking for-are -to increase the efficiency of the model for faster and more accurate detection of the parts or part families which are finished and as we mentioned they are either ready to be used as individual unit or assemble ones to the other production parts as well as kept to be used as spare parts or for any other application processes.

Dispersion properties of air-clad and silica-coated silicon photonic wires for nonlinear applicat... more Dispersion properties of air-clad and silica-coated silicon photonic wires for nonlinear applications are investigated with exact solutions of Maxwell's equations. We show that the GVD of silicon nanowires can be tailored for different wavelengths in the infrared region of the spectrum. In comparison, air-clad silica tapered fibers require diameters of several micrometers in order to extend the zero dispersion points to the infrared wavelengths. By immersing silica wires in liquid we can obtain a minimum and flat GVD region in the infrared.

The laser light penetration into the skin in these wavelengths is deep (3-5 mm). Applying new stable materials for emitting NIR wavelengths in tumor positions can help cancer treatment. In this paper, synthesis of the conjugated core-multishell Ag/SiO 2 /Ag and Au/SiO 2 /Au quantum dots (QDs) with indocyanine green (ICG) is done and their theoretical and experimental absorptions and emissions in the NIR region are investigated. Thus, heat generation (high-resolution medical imaging capabilities) and emission enhancement are explained and described based on the FRET model for the proposed core-multishell QDs and it is shown that Ag/SiO 2 /Ag with ICG presents 4 times higher emission rate versus ICG alone in NIR region. Also, because of the plasmon hybridization and also resonance light penetration enhancement, the temperature in tissues increases that is useful for photothermal therapy and NIR high-resolution medical imaging for deep tissues. As an alternative application, these nanoparticles with amazing features are used as a heat source in cancer treatment for shallow and deep tissues. Finally, it is shown that Ag/SiO 2 /Ag QDs are the best solution for this purpose.

A light-emitting diode can serve both as an illumination source in an environment and as a data transmitter. Nevertheless, plenty of complications stand in the way of developing VLC technology, including the low response time of waveguides and detectors and the field of view dependence of such devices. To cover those challenges, one approach is to develop a superior optical antenna that does not have a low response time related to phosphorescence materials and should also support concentrating light from the surroundings with a wide field of view. This research paper presents an optimized cylindrical optical antenna with benefits, such as affordable cost, fast response time due to high-efficient nanomaterials, and a wide field of view (FOV). The proposed structure avoids the need for intricate tracking systems and active pointing to the source, but it can also be ...

For this purpose, about 100 compounds that had the potential to emit blue, green, and red lights were selected, and simulation was performed using the discrete dipole approximation (DDA) method, in which the shell layer was selected to be SiO2 or TiO2 in the first step. Among the simulated compounds with SiO2 or TiO2 shells, Se/SiO2 and BTiO3/SiO2 were selected as blue light emitters with high intensity and narrow bandwidth. Accordingly, CdSe/SiO2 nanoparticles were selected as green light emitters and Au/TiO2 for the red light. As the surface of the nanoparticles in their optical properties is important, reactivation of the nanoparticles’ surface is required to reach the high-intensity peak and resolution. To this end, in the second step, the surface of Se and CdSe nanoparticles reacted with ethanolamine, which can make a strong bond with...
