Radio frequency induction - definition of Radio frequency induction in Encyclopedia (116 words) |
 | Radio frequency induction or RF induction is an electrical phenomenon in which an electromagnetic wave passing through a conductor causes electric current to flow through it. |
| It is a special case of electromagnetic induction. |
| A common use of RF induction is induction heating (also called eddy-current heating), a method of rapidly heating a conducting material. |
| Antenna (radio) - Wikipedia, the free encyclopedia (2853 words) |
| The polarization of an antenna or orientation of the radio wave is determined by the electric field or E-plane. |
| At such frequencies, signals are reflected very effectively by the ionosphere; however, at these frequencies there are many forms of natural radio noise, including the noise produced by lightning. |
| The Phased array antenna is a group of independently fed active elements in which the relative phases of the respective signals feeding the elements are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions. |
