Light beam’s magnetic
field must be shifted for
½·π radians in respect
to electric one to
achieve continuity of
energy conservation
along the path,
formalized:
½·ε·E²+½·μ⁻¹·B²=Const.
This is the only way to
conserve light energy in
propagation.
This presentation
supports Poynting vector
and energy conservation,
but it doesn’t support
polarisation of light.
