能量吸收干涉测量法在谱域中呈现，以便更容易地表示层状介质的场。 A formulation comprising a single interface between semi-infinite media is presented and a compact representation of the fringe pattern is obtained assuming that two sources with varying relative phase are used.考虑了连续有损层和非常细的平行带的极限情况，并讨论了不同的全波方法。仿真结果显示，当源放置得更靠近有损介质时，吸收介质的结构如何变得可见。
Energy absorption interferometry is presented in the spectral domain in order to allow an easier representation of fields for layered media. A formulation comprising a single interface between semi-infinite media is presented and a compact representation of the fringe pattern is obtained assuming that two sources with varying relative phase are used. Limit cases of continuous lossy layers and of very fine parallel strips are considered and different full-wave approaches are discussed. Simulation results show how the structure of the absorbing medium becomes visible when the sources are placed closer to the lossy medium.
