Maxwell's equations theoretically introduce the hypothesis of "displacement current", stating that in a vacuum, a changing electric field can induce a changing magnetic field. Based on this, Maxwell predicted the existence of "electromagnetic waves" in a vacuum. The latest research indicates that the theory of "electromagnetic waves" has never been experimentally verified. The experiment conducted by German physicist Hertz in 1887 did not prove the existence of "electromagnetic waves" but rather demonstrated that wireless communication could be achieved by independent "electric field waves". Further research reveals that the hypothesis of "displacement current" is theoretically inconsistent. The simplest and most convincing way to verify the correctness of Maxwell's "electromagnetic wave" theory is to independently measure the electric field intensity and magnetic field intensity of electromagnetic radiation in wireless communication, and then determine through experiments whether the electric field energy density is equal to the magnetic field energy density. This verification experiment is based on the 3-meter method of EMC electromagnetic compatibility standards. A half-wave dipole dual-antenna configuration with reverse attenuation is used to cancel out the magnetic fields generated by the conduction currents of the two antennas, and the electric field intensity and magnetic induction intensity in the far-field of electromagnetic radiation are independently measured. The verification experiment shows that the electric field energy density is 137.6 times that of the magnetic field energy density, and the experimental result is 137.6 times the theoretical value of the "electromagnetic wave" theory. In this verification experiment, the relative error of the electric field intensity measurement is +/- 5%, and that of the magnetic field intensity measurement is +/- 40%. The experimental results are real and valid. This experiment fully proves that, whether in the near-field or far-field, the electromagnetic fields originate from the conduction current of the antenna. In a vacuum, without the participation of charges, a changing electric field cannot generate a changing magnetic field, and a changing magnetic field cannot generate a changing electric field. "Electromagnetic waves" do not exist in the objective physical world.
