Indoor Propagation of Electromagnetic Waves with Orbital Angular Momentum at 5.8 GHz

Propagation of electromagnetic waves with orbital angular momentum OAM is investigated in indoor environments. The OAM modes generated by circular patch array antennas are used. With proper alignment and suppressed multipath, the OAM modes can transport multiple wireless data stream at the same time. Through measurements and ray-tracing simulations, it is found that the advantages of OAM modes are limited if those two conditions are not satisfied. It is also found that multipath effect can be enervated by using narrow beam antennas. Along with those approaches, orbital angular momentum OAM of electromagnetic waves receives interest in that it can increase the capacity of wireless communications.

Book excerpts: This text provides a broad and applications-oriented introduction to electromagnetic waves and antennas.

Current interest in these areas is driven by the growth in wireless and fiber-optic communications, information technology, and materials science. Communications, antenna, radar, and microwave engineers must deal with the generation, transmission, and reception of electromagnetic waves. Novel recent developments in materials, such as photonic bandgap structures, omnidirectional dielectric mirrors, and birefringent multilayer films, promise a revolution in the control and manipulation of light. These are just some examples of topics discussed in this book. The text is organized around three main topic areas:. The text also emphasizes connections to other subjects, including digital signal processing, digital filter design and Fast Fourier Transform.

Antennas and Electromagnetic Radiation

In radio engineering , an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In reception , an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductors elements , electrically connected to the receiver or transmitter. An antenna may include components not connected to the transmitter, parabolic reflectors , horns , or parasitic elements , which serve to direct the radio waves into a beam or other desired radiation pattern.

Electromagnetic Waves and Antennas by Sophocles J. Description : This book provides a broad and applications-oriented introduction to electromagnetic waves and antennas.

Exercises I2 throughI5 pertain to the classical picture of electromagnetic radiation. Classical Electromagnetic Radiation-Jerry Marion Classical Electromagnetic Radiation, Second Edition focuses on the classical electrodynamics with emphasis on radiation problems and the wave attributes of the electromagnetic field. Radiation is energy.

Ее прозрачный куполообразный потолок в центральной части поднимался на 120 футов. Купол из плексигласа имел ячеистую структуру - защитную паутину, способную выдержать взрыв силой в две мегатонны. Солнечные лучи, проходя сквозь этот экран, покрывали стены нежным кружевным узором. Крошечные частички пыли, пленницы мощной системы деионизации купола, простодушно устремлялись вверх широкой спиралью. Наклонные стены помещения, образуя вверху широкую арку, на уровне глаз были практически вертикальными.
