The photon in free space comprises a partial two-dimensional covering of a spherical shell by great circle electric (E) field lines and orthogonal great circle magnetic (B) field lines wherein the sphere has the size of the photon wavelength. The photon field lines move as an ensemble at light speed and appear in the sub-light speed laboratory frame as one of linear or right or left-handed circularly polarized E and B fields that vary harmonically in time and space over the period corresponding to the wavelength as the photon propagates past an observer. The photon carrying h bar of angular momentum in its E and B field lines impacts the supercurrent of the two-dimensional spherical atomic electron membrane to cause a reaction current that in turn causes the photon to be captured on the inner surface of the electron current. The first step of this photon absorption process is the conversion of the B field lines to electric field lines of the same pattern as that of the photon. The E field lines rotate over the inner electron surface in the same manner as the free electron current when it binds to a nucleus to form a bound atomic electron (https://brilliantlightpower.com/electron-binding-and-ionization-simulation/). Specifically, the photon electric field line pattern matches the great circle current pattern of the bound electron wherein the photon fields and the electron current as a source current are phase matched. The field lines also circulate at light speed such that the relativistic local field at the surface of the electron is radial. The electric field of the photon superimposes the electric field of the nucleus to partially cancel the corresponding central force such that the electron membrane expands further away from the nucleus to form an excited state. The multipolarity of the photon is conserved by giving rise to a conservative time and spatially harmonic charge density wave that travels in the electron current about an axis of the electron. This modulation of the uniform spin current density corresponds to electron orbital angular momentum; in addition to the spin angular momentum of the electron inherent is its great circle current density pattern of uniform charge density.
