The Accepted Theories Have Been Overturned

Description: In the domain of microwave absorption materials research, a perplexing confusion has arisen regarding films and materials. This confusion stems from the inappropriate extrapolation of reflection loss (RL/dB) findings from films to materials. Consequently, erroneous theories have emerged, including the misguided development of impedance matching theory, which relies on the inadequately defined concept of energy penetration—an idea ill-suited for films. Additionally, it has led to the formulation of an incorrect quarter-wavelength theory, overlooking phase effects originating at film interfaces. Most notably, it has resulted in an inaccurate absorption mechanism for films, which should be replaced by the wave cancellation theory. Remarkably, these misconceptions have endured within a contemporary research domain for a substantial period, yet they can be rectified through the application of college-level physics and mathematical skills typically taught at the junior middle school level.

While it might appear straightforward to overturn the current theoretical system, based on fundamental principles, it has proven to be a formidable task due to the long-standing prevalence of incorrect theories in the field. This flawed theoretical framework, which mistakenly asserts its roots in transmission line theory, has misapplied this theory in practice. Consequently, genuinely robust new theories grounded in wave mechanics have been unjustly perceived as conflicting with common sense. Despite our years of dedication to this subject and our multifaceted approach, involving numerous papers published in reputable journals, the scientific community has not yet embraced the new theory. The erroneous practices persist without recognition of our perspectives, despite our papers garnering significant viewership and downloads. Even our new manuscripts, such as those listed below:

continue to face challenges in passing the initial screening process by the editors of numerous journals. Interestingly, many of the reviewers who strongly criticized our manuscripts in previous submissions have refrained from submitting comment letters when our papers were eventually published in alternative journals, indicating their inability to provide relevant counterarguments. Challenges are warmly embraced.

The innovative new theory, contrasting mainstream theories, is rooted in wave mechanics and has unveiled previously unrecognized physics exclusive to films. Scientists may encounter certain challenges when considering our arguments, as they introduce many new concepts that contradict long-held mainstream theories. For instance, we have demonstrated that the voltage amplitude of certain beams can exceed that of the incident beam, seemingly at odds with the principle of energy conservation. Additionally, unexpected results have emerged, such as the observation that maximizing the absorption also maximizes the transmitted beam into open space. It has been found that the optimal absorption film may be composed of material with lower absorption power and reduced microwave penetration, as maximizing material attenuation and penetration does not guarantee the film's maximum absorption. These contradict common conclusions, as RL serves as a parameter for the film rather than the material, challenging the conventional treatment of film and material as equivalent entities. Moreover, the fact that the behavior of the interface in its isolated state differs from that in the film remained unnoticed for an extended period.

We have recently come across a study that employs wave cancellation theory aligned with our proposed theory in the design of materials for absorption films:
