On The Theory of Field Pattern Synthesis.(Dept.E)
Autor: I. Mandour, A. El-Sohly, H.A. El-Mikati
Publikováno v: MEJ. Mansoura Engineering Journal. 4:11-32
Uniform array synthesis is treated as a problem of approximation in the mean square sense and in the Sobolev sense are considered. Following Tichonov's regularization technique for solving inverse problems , the array excitation current is subjected

Publikováno v: MEJ. Mansoura Engineering Journal. 6:55-62
A method for synthesis of chebyshev FIR digital filters is presented. The best approximation in the chebyshev (L ) sense is obtained making use of the method of successive projections, which reduces the problem to one of finding a point in the inters

Boundary Element-Conjugate Gradient Method for Electromagnetic Scattering by Conducting Cylinders.(Dept.E)
Autor: H.A. El-Mikati
Publikováno v: MEJ. Mansoura Engineering Journal. 12:1-8
A boundary element-conjugate gradient memory economic technique is presented for the analysis of the scattering of an E or H - wave by a conducting cylinder of arbitrary cross-section. The case of internal resonance is treated using the developed tec

Study of The Characteristics of A Line-Fed Two-Layers Coupled Rectangular Patch Antenna Using FDTD Method.(Dept.E)
Autor: H.A. El-Mikati, Abd Elaziz A. Mitkees, A.N. Mahmoud, Maher Abd Elrazzak
Publikováno v: MEJ. Mansoura Engineering Journal. 27:14-25
In the present work, the analysis and design of a line fed two-layers coupled rectangular patch antenna is presented. The return loss, the input impedance, and the radiation pattern of the proposed structure are determined using the finite difference

Finite Difference Time Domain Analysis of Two Dimensional Photonic Bandgap Devices(Dept.E)
Autor: H.A. El-Mikati, Nihal F. F. Areed, Salah S. A. Obayya
Publikováno v: MEJ. Mansoura Engineering Journal. 32:1-10
A Finite Difference Time Domain (FDTD) analysis has been effectively applied to investigate the transmission of the transverse electric polarized pulses in photonic crystals arrangements. The photonic bandgap of 2-D photonic crystal with square and v

Highly birefringent slotted core photonic crystal fiber for terahertz waveguiding
Autor: Mohamed Farhat O. Hameed, A. M. Heikal, Salah S. A. Obayya, H.A. El-Mikati, Aboulwafa M. Singer
Publikováno v: Optical and Quantum Electronics. 53
A novel porous core photonic crystal fiber (PC-PCF) is suggested and analyzed for terahertz waveguiding. The PC-PCF has a TOPAS background material with suspended asymmetric slotted core. Therefore, high birefringence of 0.09 is achieved with small m

CIRCULAR, HEXAGONAL AND OCTAGONAL ARRAY GEOMETRIES FOR SMART ANTENNA SYSTEMS USING HYBRID CFO-HC ALGORITHM
Autor: Ahmed M. Montaser, Adel B. Abdel-Rahman, Korany R. Mahmoud, H.A. El-Mikati
Publikováno v: JES. Journal of Engineering Sciences. 40:1715-1732
In this paper, circular, hexagonal and Octagonal array geometries for smart antenna applications are compared. Uniform circular (UCA), uniform hexagonal (UHA) and uniform Octagonal arrays (UOA) with 24 half-wave dipole elements are examined. An effic

Sample-by-sample and block-adaptive robust constant modulus-based algorithms
Autor: Said Elnoubi, H.A. El-Mikati, Ayman Elnashar
Publikováno v: IET Signal Processing. 6:805-813
In this study, a robust sample-by-sample linearly constrained constant modulus algorithm (LCCMA) and a robust adaptive block-Shanno constant modulus algorithm (BSCMA) are developed. The well-established quadratic inequality constraint approach is exp
