Inverse Problems of Antenna Theory
ISBN: 9783659598531 / Angielski / Miękka / 2014 / 212 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The synthesis problem solves a task of creating antennas with a high performance. One can use two methods. The first method is the creation of new antennas on a basis of new ideas, new materials and new technological opportunities. As an example of new antennas one can call volume (three-dimensional) self-complementary antennas. They are structures of electric and magnetic radiators, placed on cylindrical, conical and parabolic surfaces of revolution. Another method of solving the inverse problem is determining parameters, providing optimum electrical characteristics of known antennas. Thus,...

Antenna Engineering: Theory and Problems
ISBN: 9780367782481 / Angielski / Miękka / 2021 / 408 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The book deals with theoretical and experimental research of antennas. The presentation is based on the electromagnetic theory. It begins with the theory of thin antennas. Thin antennas represent one of the main types of radiators, thus the theory of thin antennas is the basis of the antennas analysis. Special attention is paid to the integral equation of Leontovich-Levin for a current along a straight thin-walled metal cylinder, which is equivalent to the equation of Hallen with a precise kernel. Together with the analysis of various types of antennas, the book deals with the problems of...

Wide-Range and Multi-Frequency Antennas
ISBN: 9781138487444 / Angielski / Twarda / 2019 / 254 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. Expanding the range of antenna frequency is the main objective of this book. Solutions proposed are based on the development of new theoretical methods for analyzing and synthesizing antennas. The book shows that concentrated capacitive loads connected along linear and V-antennas provide a high level of matching with a cable over a wide frequency range and improves directional characteristics of antennas, i.e. increases the communication distance. New theoretical methods are proposed for analysis and synthesis of antennas under consideration: 1) method of calculating directional...

Method of a Complex Potential in Antenna Engineering
ISBN: 9783659562297 / Angielski / Miękka / 2014 / 192 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In the offered book the method of a complex potential is generalized, firstly, to piecewise homogeneous media and, secondly, to three-dimensional structures. Three-dimensional conic and parabolic problems are reduced to two-dimensional (cylindrical) one, and the metal bodies' coordinates in these problems are connected with simple equalities. That permits to propose the general theory of flat and volume complementary and self-complementary antennas and to develop the procedure of calculating these antennas and also antennas located on the pyramid sides. In the book concrete problems are...

Physics of Tsunamis
ISBN: 9789048180073 / Angielski / Miękka / 2010 / 327 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Till the very end of the twentieth century tsunami waves (or waves in a harbour, translated from Japanese) were considered an extremely rare and exotic natural p- nomenon, originating in the ocean and unexpectedly falling upon the seaside as gigantic waves. The 26th of December 2004, when tsunami waves wiped out, in a single day, more than 250,000 human lives, mourned in many countries, turned out to be a tragic date for all mankind. The authors of this book, who have studied tsunami waves for many years, - tended it to be a systematic exposition of modern ideas concerning The mechanisms of...
