Where magnetic field intensity; electric field; permittivity, distance, time. The values of , , and respectively are:
- (1)1, 1, 1, 1
- (2), 1, 2, 1
- (3)1, , , 1
- (4), , , 1
We corrected a printing error in the original paper
Source printed “ magnetic field” (with in tesla no option fits); corrected to the intended “ magnetic field intensity” (A/m).
