WebOrthogonal E and H field are the property of a propagating EM wave in free space. Around an antenna, within a few wavelengths distance, there are "near field" or "Fresnel" regions in which there are non-propagating waves. These waves do not have necessarily orthogonal fields. More detail can be found in a reference text such as Antenna Theory ... WebDescription. For an environmentally-minded dish soap, try Field & Future by H-E-B Dishwashing Liquid.

From a more abstract viewpoint, H and B aren't even the same type of geometrical object. H is a [twisted-]1-form in space, which is associated with a line-integral, and B is a 2-form in space, which is associated with a surface-integral. Similarly, E is a 1-form and D is a [twisted-]2-form. WebThe lowest H-field exposure levels occur at 100-300 MHz. The ANSI standard sets the maximum E-field limits between 30 and 300 MHz at a power density of 1 mW/cm 2 (61.4 V/m) in controlled environments-but at one-fifth that level (0.2 mW/cm 2 or 27.5 V/m) in uncontrolled environments. how to draw boat on water
