Interference-Induced Energy Anomaly

In light of the ongoing debates regarding possible violations of the energy conservation law (ECL), we investigate a specific point of doubt about energy conservation by coherent interference of the two electromagnetic waves. The energy deviations from ECL are presented in terms of power flows and compared with those predicted by the ECL. Specifically, when two radiation sources are placed in close proximity, coherent interference between the two waves can occur consistently at every point throughout space, leading to a net increase or decrease in the total radiative power due to the constructive or destructive interference respectively. In extreme cases, it results in either a doubling or vanishing the combined power of the two sources. The energy abnormality has been clearly observed at the stage of wave superposition. Keeping this in mind, we create a model to produce the coherent interference through pure wave performance, isolating the unique physics features from other implications. To this end, we design a parabolic reflection system and measure the power input and output in terms of power flows, and ultimately substantiate a valid basis for our inquiry.
