WebThe far field projection functions assume that the EM fields are zero beyond the edge of the monitor. This effectively truncates the near fields at the monitor edge. Use spatial filtering to minimize this issue. The material can be dispersive as long as the loss is negligible, ie k< WebThe far field is the region far from the antenna, as you might suspect. In this region, the radiation pattern does not change shape with distance (R). Although the E- and H- fields still die off as 1/R, the power density dies … The near field and far field are regions of the electromagnetic (EM) field around an object, such as a transmitting antenna, or the result of radiation scattering off an object. Non-radiative near-field behaviors dominate close to the antenna or scattering object, while electromagnetic radiation far-field … See more In a normally-operating antenna, positive and negative charges have no way of leaving the metal surface, and are separated from each other by the excitation "signal" voltage (a transmitter or other EM exciting … See more The near field itself is further divided into the reactive near field and the radiative near field. The reactive and radiative near-field designations are also a function of wavelength (or distance). However, these boundary regions are a fraction of one wavelength within … See more Local effects • Fraunhofer diffraction for more on the far field • Fresnel diffraction for more on the near field See more • George F.
