English translation of the paper "Electromagnetic field inside a plane-parallel layer in the resonant absorption regime" (1962) by A. P. Khapalyuk: Pioneering study on coherent perfect absorption
In 1962, Belarusian physicist A. P. Khapalyuk has published the paper [Doklady Akademii nauk BSSR, volume 6, issue 5, pages 301-304] devoted to the effect of resonant absorption of light in a layer of matter. This work can be considered as a first study of the phenomenon known today as coherent perfect absorption (CPA). Unfortunately, the paper by A. P. Khapalyuk was published in a local journal in Russian and is almost unknown to the English-language scientific community. Here, we give the fir…
