NUMERICAL ELECTROMAGNETICS FOR PERSONAL DOSIMETRY OF CELLULAR PHONES
ISBN: 9783843368339 / Angielski / Miękka / 360 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. An approach to hybridisation of the Method of Moments (MoM) and the Finite Difference Time Domain (FDTD) method is investigated. This hybrid method is capable of analysing a system of multiple discrete regions by employing the principle of equivalent sources to excite their coupling surfaces. Examples are provided to indicate both the potential and limitations of the hybrid method. It is shown that this technique has the great advantage of accurately modelling complex and arbitrarily oriented mobile telephone handset antennas, especially typical helical types, in the proximity of a detailed...

Circular-Polarized Antennas for Satellite Wireless Communications
ISBN: 9783845478777 / Angielski / Miękka / 156 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The objectives of this research work are to investigate, design and implement circularly-polarized antennas to be used for handheld satellite mobile communication and wireless sensor networks. Several antennas such as Quadrifilar Spiral Antennas (QSAs), two arm Square Spiral and stripline or coaxially-fed microstrip patch antennas are developed and tested. These antennas are investigated and discussed to operate at L band (1.61-1.6214GHz) and ISM band (2.4835-2.5GHz) A Genetic Algorithm in cooperation with an electromagnetic simulator has been introduced to provide fast, accurate and reliable...

Computationally Intelligent CFD
ISBN: 9783843355193 / Angielski / Miękka / 2010 / 224 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In this work, the concept of evolutionary search is utilized as a versatile CFD solver. Specifically, a real-coded genetic algorithm, mimicking the natural evolution process, is used to minimize the residuals resulting from a finite difference discretization. While most gradient-based methods can suffer from divergence or slow convergence, the evolutionary solvers heuristic nature allows it to avoid solving the resulting systems of equations, thereby precluding many convergence difficulties and avoiding stiffness-related problems. Furthermore, these stochastic optimization techniques work...
