That's simply false. Using Fourier analysis, I reduce anything other
than a sinusoid to multiple sinusoidal RF excitations, perform the
sinusoidal analysis, and then use superposition to find the answer.

You need to expand your solution space. Some problems are so much
easier to solve in the time domain.

I can't even imagine doing some problems in the frequency domain.
Let's see: I turn on my flashlight maybe once per week, so the
fundamental is 1.6e-6 Hz, and say the risetime is 1 millisecond
-- my head hurts already -- that's about 600,000,000 harmonics to
be computed. No wonder you give up on some problems so readily.

I also reject any example where Maxwell's equations do not work. Your
insistance that magical waves can somehow exist during DC steady-state
violates the known laws of physics.

It is not my insistence. It follows from the math.

Besides if you convert it to the frequency domain you should
be happy that they exist since they then align with your
understandings.

EM waves CANNOT exist during DC
steady-state because electrons are traveling at a constant velocity.

Are you sure you meant this? The electron velocity changes? Or did
you mean the wave velocity? Nope. That does not work either.

You can measure DC voltage with an AC voltmeter but that doesn't
change DC voltage to AC voltage.

And for especial fun... Why are you sure DC is so special?
v(t)=A cos(wt)
describes a sinusoid. It has the parameter w to specifiy the
frequency. Set it to 0, and voila: DC. It falls right out
of the same definition as is used for a sinusoid. It is a
sinusoid.
