  "abstract": "Conventional encrypted optical and acoustic meta-holograms only focus on the encrypted hologram in amplitude channel, viz. modulating spatial amplitude to encrypt or project a holographic image, which may lead to information leakage in other channels. In this research, the unique concept of four-channel amplitude-phase-Janus-encrypted acoustic metaholograms is proposed, demonstrating remarkable capabilities of generating, encrypting, and decrypting both amplitude and phase holographic images on both sides of a metascreen. The flexible and decoupled manipulation mechanism for the amplitude-phase of the bidirectional acoustic waves used in our concept offers multiple possibilities to apply unconventional amplitude-phase-encryption methods.\n\nIn this work, our system enables single-input, two-faced four-channel encryption, which substantially increase the communication capacity of conventional acoustic holograms, and the security of amplitude-phaseencryption is demonstrated. Our work can lead to concrete applications including multi-channel acoustic field communications with high security framework, acoustic illusion and cloaking in non-transparent media, etc.",
