膜的微波吸收机理

Microwave absorption mechanism for film

微波吸收现行理论将膜和材料混淆,把只能用于膜的反射损失(RL)性质用来表征材料,于是建立了错误的阻抗匹配理论和错误的膜吸收机理.阻抗匹配理论的不严谨表现为它有不同的定义,结果导致荒谬的结论如材料吸收的微波比进入材料的微波更多.这个事实说明阻抗匹配理论将孤立界面和在膜中的界面相混淆.阻抗匹配理论是建立在不可定义的物理量基础上的理论,存在严重缺陷.主流理论认为是材料本身具有多个吸收峰的性质导致(RL)有多个极小值.实际上均匀材料中的任何位置其微波吸收能力是一样的.微波在材料中传播的越远,被吸收的就越多,不会出现吸收峰.因而主流理论中膜的吸收峰又被错误地归结为材料的共振吸收.采用理论方法和自己实验室的实验数据,在波相消干涉的基础上建立了不同于当前主流理论的膜吸收机理并开拓性地应用了新理论.并指出文献报道的实验数据并不支持主流理论.同时通过已经发表的数据说明材料和膜的吸收机理不同,膜的吸收峰不是材料本身的属性,微波中的阻抗匹配理论应该用波的相消干涉理论取代.膜的多个吸收峰是膜特有的能量守恒所要求的、是角度效应的结果,需要用波的相消干涉分析,与材料的共振吸收没有任何关系.主流微波吸收理论混淆了实数和复数运算的不同规律.

The current theory of microwave absorption confuses film and material,and uses reflection loss(RL)for device to characterize material,thus establishing the wrong impedance matching theory and wrong absorption mechanism for film.The imprecision of impedance matching theory is manifested by its different definitions,resulting in absurd conclusions such as that more microwaves can be absorbed by the material than those enter the film material.This fact indicates that impedance matching theory confuses isolated interface with it in film.The impedance matching theory is based on undefined physical quantities and has serious flaws.This mainstream theory believes that the material by itself offers multiple absorption peaks,resulting in multiple absorption peaks represented by RL.In fact,the microwave absorption power is the same at any position in a uniform material.The farther the microwave propagates in the material,the more it is absorbed and there will be no absorption peak.Therefore,in the mainstream theory,the absorption peaks of the film are mistakenly attributed to the resonance absorption of the material.Based on wave cancellation using theoretical methods and experimental data from our own laboratory,we have established absorption mechanism for film different from that in current mainstream theories and have innovatively applied our new theories.We have also pointed out that the experimental data reported in the literature does not support the mainstream theories.Through published data,this work demonstrates that the absorption mechanisms of material and film are different.The absorption peaks of film are not attributing of the material itself,and the impedance matching theory of absorption films should be replaced by the wave cancellation theory.The multiple absorption peaks of a film are required by the energy conservation unique to film and are the result of angle(or phase)effects,whose analysis requires wave cancellation theory,the origin of which is independent of the resonance absorption of the material.The mainstream microwave absorption theory also confuses the difference mathematics between real and complex number.
