However, I just want to know if an EM wave can have the same excitation effects as magnetic stimulation.
No. They are different effects.
What you call an EM wave, is actually an ionic current from skin electrodes, that flows through the tissue.
Magnetic stimulation penetrates the cranium to induce ion currents, within the brain.

In your answer you also state that the energy delivered is in the time field of a carrier and therefore pulsed.
If the stimulation was by heating, then the stimulation is pulsed by the 5 Hz beat. The power used was insufficient to significantly heat the tissue, so local heating would not stimulate the brain at 5 Hz. Higher power could heat the brain, but the thermal time constant would attenuate the 5 Hz signal, so there would only be, a general cooking of the tissue.
If the stimulation is by ionic currents, then the beating 2 kHz currents, have too high a frequency to have a strong stimulating effect.

... so in my opinion an EM wave can excite the neurons given that it is a simple depolarization of the ionic channels, ...
High currents at 2 kHz may depolarise ion channels, but that will not stimulate a specific part of the brain. The small currents used, 1 mA, are unlikely to have an effect at 2 kHz.
The test subject was a cadaver, not a living person, so we do not have a report from the patient/victim. We do not know if the treatment stimulated anything, or made them feel different.

so in summary what do you think?
The paper is a confoundation of unrealistic expectations. It is a distraction from reality.
The stimulation is NOT really by EM fields, but by ionic currents from surface electrodes.
Narrow rivers of ionic current do not exist, so will NOT focus the effect onto a small region of tissue.
The 2 kHz current is TOO high a frequency, to directly stimulate neurons.
There is NO effective, or real 5 Hz beat in the brain. NO ionic beat, NO thermal beat.
Do not be distracted. Keep using magnetic stimulation.
