radiated field उदाहरण वाक्य

The EFIE describes a radiated field "'E "'given a set of sources "'J "', and as such it is the fundamental equation used in antenna analysis and design.
It is a very general relationship that can be used to compute the radiated field of any sort of antenna once the current distribution on it is known.
It is the combination of radiated field and receptive ground loop that causes problems, and the situation can be improved by attention to either one, or both of these.
Rather, in the near field, it is sometimes useful to express the contributions as a sum of radiating fields combined with evanescent fields, where the latter are exponentially decaying with.
His research interests are in low-and high-frequency methods for antennas propagation, and scattering; smart antennas for wireless communication; penetration and scattering of High Intensity Radiated Fields ( HIRF ); and multipath propagation.

The reflected field is due to the currents on the FSS ( the field radiated by the FSS ) and the transmitted field is equal to the radiated field plus the incident field, and differs from the reflected field only for the " m " p = 0, " n " = 0 order ( the zero order ).
The simplest argument would be that the fields goes to zero at infinity for a localized source, but this argument fails in the case of lossless media : in the absence of absorption, radiated fields decay inversely with distance, but the surface area of the integral increases with the square of distance, so the two rates balance one another in the integral.
