In the following text quotations from M.W. Evans' GCUFT book [1] appear with equation labels [1.nn] at the left margin.

The assertion of O(3) symmetry is at the center of M.W. Evans'
considerations since 1992. He claims
that each plane circularly-polarized electromagnetic wave is
accompanied by a constant longitudinal field **B**^{(3)},
a so-called "ghost field".
In addition to numerous papers, with far reaching implications as e.g. in
[2] and [3], M.W. Evans is author of *five* books
on "The Enigmatic Photon" dealing with the claimed O(3)-symmetry of
electromagnetic fields. His hypotheses have met many objections. The reader
will find a historical overview written by A. Lakhtakia in
(5; Sect.5].

M.W. Evans considers a circularly polarized plane electromagnetic wave propagating in z-direction, cf. [1; Chap.1.2]. Using the electromagnetic phase

[1.38] Φ = ω t − κ z ,

where κ = ω /c , he describes the wave relative to his
complex circular basis [1.41] derived from the cartesian basis vectors
**i**, **j**, **k**. The magnetic field is given as

[1.43/1]
**B**^{(1)} = ^{1}/_{sqr(2)} B^{(0)}
(**i** − *i* **j**) e^{i Φ},

[1.43/2]
**B**^{(2)} = ^{1}/_{sqr(2)} B^{(0)}
(**i** + *i* **j**) e^{− i Φ} ,

[1.43/3]
**B**^{(3)} = B^{(0)} **k** ,

and satisfies the "cyclic O(3) symmetry relations"

[1.44/1]
**B**^{(1)} × **B**^{(2)} = *i* B^{(0)} **B**^{(3)}* ,

[1.44/2]
**B**^{(2)} × **B**^{(3)} = *i* B^{(0)} **B**^{(1)}* ,

[1.44/3]
**B**^{(3)} × **B**^{(1)} = *i* B^{(0)} **B**^{(2)}* .

Especially equ.[1.43/3] defines the "ghost field" **B**^{(3)}
which is coupled by the relations [1.44] with the transversal
components **B**^{(1)} and **B**^{(2)} .

M.W. Evans' **Cyclic Theorem** is the statement that each plane circularly
polarized wave [1.43/1-2]
is accompanied by a longitudinal field [1.43/3], and the associated fields
fulfil the cyclic equations [1.44].
M.W. Evans considers this O(3) hypothesis as a **Law of Physics**.

2. Checking the superposition property of the O(3) hypothesis

Instead of [1.38] we consider a phase shifted wave with the more general phase function

(2.1)
Φ_{α}(t,z) = ω t - κ z + α = Φ(t,z) + α

which can be understood as a time shifted wave where the time shift is
t_{o} := - ^{α}/_{ω}:

(2.2)
Φ_{α}(t,z) = Φ(t-t_{o},z) .

We use the phase Φ_{α} in [1.43] to obtain the time-shifted magnetic field

(2.3)
**B**^{(1)}
= ^{1}/_{sqr(2)} B^{(0)}
(**i**−*i***j**) e^{i(Φ+α)} ,

(2.4)
**B**^{(2)}
= ^{1}/_{sqr(2)} B^{(0)}
(**i**+*i***j**) e^{−i(Φ+α)},

(2.5)
**B**^{(3)}
=
γ B^{(0)} **k** ,

where we have introduced a coefficient γ that should equal 1
following M.W. Evans while in classical electrodynamics γ =0 .

Now we consider the wave generated by the superposition of two waves with
the phase functions Φ_{α} and Φ_{−α} ,
respectively, and α such that cos α < 1 .
According to the *superposition principle* the total field is then

(2.6)
**B**^{(1)} = ^{1}/_{sqr(2)} B^{(0)}
(**i**−*i***j**) [e^{i (Φ+α)} + e^{i (Φ−α)}]
= ^{1}/_{sqr(2)} B^{(0)}
(**i**−*i***j**) e^{i Φ} 2 cos α ,

(2.7)
**B**^{(2)} = ^{1}/_{sqr(2)} B^{(0)}
(**i**+*i***j**) [e^{−i(Φ+α)} + e^{−i(Φ−α)}]
= ^{1}/_{sqr(2)} B^{(0)}
(**i**+*i***j**) e^{−iΦ} 2 cos α ,

(2.8)
**B**^{(3)} = 2 γ B^{(0)} **k** .

Considering the first two (transversal) components we recognize that the
superposition yields the original wave [1.43/1-2] multiplied by the factor
2 cos α . Hence, according to M.W. Evans' O(3)
hypothesis [1.43/3] it should be accompanied by a longitudinal component
2 γ cos α · B^{(0)} **k** with γ=1 .
The superposition principle, however, yields
**B**^{(3)} = 2 γ B^{(0)} **k** (Eq. (2.8)).
Since we assumed cos α < 1 , this is a contradiction.
Only the classical case γ=0
is compatible with the superposition principle, and
M.W. Evans' "ghost field" cannot exist.
