Abstract: A non-Hermitian complementary metamaterial (NHCMM). Acoustic transmission systems including an acoustic wave generator configured to generate an acoustic wave and propagate the acoustic wave through a tissue of a specimen, and the NHCMM, which is configured to add a first amount of energy amplification coherently to the acoustic wave to account for energy loss in the acoustic wave as a result of the wave propagating through the tissue of the specimen. The acoustic wave generator can be an ultrasound generator, and the tissue can be a cranium.
