    "abstract": "Generally, when imaginary part of an optical potential is non-symmetric the\nreflectivity, $R(E)$, shows left/right handedness, further if it is not\nnegative-definite the reflection and transmission, $T(E)$, coefficients become\nanomalous in some energy intervals and absorption is indefinite ($\\pm$). We\nfind that the complex PT-symmetric potentials could be exceptional in this\nregard. They may act effectively like an absorptive potential for any incident\nenergy provided the particle enters from the preferred (absorptive) side.",
