A mathematical model of the diffusion of an intense magnetic field into a thin incompressible conductor, when the magnetic field on one surface of the conductor is specified and an electromagnetic field is radi
An apparatus and method are provided to calculate the strength of an electromagnetic field radiated from an electric device according to a moment method, wherein the moment method is based on integral equations derived from electromagnetic equations. The apparatus and method include a setting unit to...
When the region around an antenna is free of obstacles, the electromagnetic fields radiated by the antenna propagate in the form of a spherical wave. The far field region comprises radial distances r from the antenna that are larger than about 2L2/λ, where L is the largest dimension of the...
1. A reflector adapted for use under a radome, wherein the radome is disposed on an exterior surface of a mobile platform and encloses an antenna, for reflecting electromagnetic radiation radiated from said antenna away from said mobile platform, said reflector comprising: an angled wall disposed...
We theoretically show that a single free electron in circular motion radiates an electromagnetic wave possessing helical phase structure, which is closely related to orbital angular momentum carried by it. We experimentally demonstrate it by interference
a Faraday screen mounted on the window of the device for separating the plasma source from the chamber, which Faraday screen can at least partially decouple the magnetic action from the electrical action of the radiated field. 10. The device according to claim 5, wherein during the transport...
(Fig.1). This allows reuse of waste heat so that less than 1 W of additional power is needed from heaters during steady-state operation. All other heat losses are channelled to the front and side panels of the propulsion system and either radiated or conducted to the spacecraft. See...
Path loss is a dilution of the transmitted energy as the radiated wavefront expands during its travel from transmitter antenna to receiver antenna. For example, when communicating from Earth to a geosynchronous satellite (at an altitude of 37,786 km) at S-band (∼2 GHz, λ≈ 0.15 m), ...
The basics ofelectromagnetic fieldsare outlined insection 11.1.4.1.Radiated fieldmeasurements can be made of either electric (E) or magnetic (H) field components. Inthe far field the two are equally representative of the power in the field, and are related by the impedance offree space: ...
The computation of the electromagnetic (EM) fields from overhead electric lines located above dissipative terrestrial areas is a classical problem which is still of interest today because of the public concern about the biological effects of field exposure. In fact, it is well known that the stron...
