Abstract
AbstractThe objective of this study is to propose a heuristic model of energy propagation due to an anomaly; electromagnetic (EM) field penetration into a continuously covered conducting enclosure (Faraday shield) from an external radio frequency source, violating the accepted model in the EM field theory. In this study, at an arbitrarily selected frequency, range of 26.965–1,800 MHz, of an external frequency source, an EM field inside the conducting enclosure was observed, contrary to expectations, which was followed by a systematic examination. Although no induced voltage could be expected inside the enclosure according to the classical theory, the experiment revealed a clear induced voltage inside, an attenuated induced voltage of −18.0 to −1.0 dB (for the range of frequencies 26.965–1,800 MHz) was observed. Hence, these results apparently contradict the established notion that an EM field cannot penetrate a Faraday shield. Rationalizing these observations and the results of the investigation leads to an alternative model to the existing models of energy propagation in free space. In this model, novel quantities named “I-Spin-energy” and “I-Spin-energy field” are defined to replace the concept of electric and magnetic fields in the classical EM theory. The proposed I-Spin-energy model is capable of explaining the unexpected presence of the EM field inside the Faraday shield as well as the induction of an alternating current in a conductor placed inside a Faraday shield along with other existing observations in physics such as those in famous Young’s double-slit experiment on interference of light, which provided the basis for the wave theory.

For frequencies of 26.965, 151.880, 500, 900, and 1,800 MHz, the power induced in the monopole conductor without and with the cubic enclosures (CuCuE) (Figure 3) is given in Table 1, where the signal strength is given in dBm
Summary
As any new revelation has a bearing on the accepted existing knowledge, some analysis of the electromagnetic (EM) field becomes expedient. The experiments shown here discuss most fundamental concepts related to the classical EM field, and these fundamental concepts are recalled with fine detail to show their contradictory nature with the observations obtained in these experiments. Energy propagation in free space has been described by the wave theory and the quantum theory. Energy is considered to propagate in the form of EM waves, which consist of selfpropagating transverse oscillating coupled waves of electric and magnetic fields perpendicular to each other and perpendicular to the direction of the propagation of energy. The solutions for linearly polarized planar electric and magnetic fields, E(r) and B(r), respectively, at any given point r relative to any arbitrary point in free space are expressed as follows:
