Generalized Transmission Line Method to Study the Far-zone Radiation of Antennas Under a Multilayer Structure
ISBN: 9783031004100 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This book gives a step-by-step presentation of a generalized transmission line method to study the far-zone radiation of antennas under a multilayer structure. Normally, a radiation problem requires a full wave analysis which may be time consuming. The beauty of the generalized transmission line method is that it transforms the radiation problem for a specific type of structure, say the multilayer structure excited by an antenna, into a circuit problem that can be efficiently analyzed. Using the Reciprocity Theorem and far-field approximation, the method computes the far-zone radiation due to...

Particle Swarm Optimizaton: A Physics-Based Approach
ISBN: 9783031005763 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work aims to provide new introduction to the particle swarm optimization methods using a formal analogy with physical systems. By postulating that the swarm motion behaves similar to both classical and quantum particles, we establish a direct connection between what are usually assumed to be separate fields of study, optimization and physics. Within this framework, it becomes quite natural to derive the recently introduced quantum PSO algorithm from the Hamiltonian or the Lagrangian of the dynamical system. The physical theory of the PSO is used to suggest some improvements in the...

Energy-Efficient Scheduling under Delay Constraints for Wireless Networks
ISBN: 9783031792533 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Packet delay and energy consumption are important considerations in wireless and sensor networks as these metrics directly affect the quality of service of the application and the resource consumption of the network; especially, for a rapidly growing class of real-time applications that impose strict restrictions on packet delays. Dynamic rate control is a novel technique for adapting the transmission rate of wireless devices, almost in real-time, to opportunistically exploit time-varying channel conditions as well as changing traffic patterns. Since power consumption is not a linear function...

Electromagnetic Scattering using the Iterative Multi-Region Technique
ISBN: 9783031005749 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this work, an iterative approach using the finite difference frequency domain method is presented to solve the problem of scattering from large-scale electromagnetic structures. The idea of the proposed iterative approach is to divide one computational domain into smaller subregions and solve each subregion separately. Then the subregion solutions are combined iteratively to obtain a solution for the complete domain. As a result, a considerable reduction in the computation time and memory is achieved. This procedure is referred to as the iterative multiregion (IMR) technique. Different...
