<p>A wave absorbing device and a wireless terminal. The wireless terminal comprises a periodic array unit, arranged at a top surface of the wave absorbing device, possessing a settable frequency selection characteristic and configured to absorb waves in a preset frequency band, the preset frequency band comprising a frequency band in which the maximum value of a specific absorption rate SAR is positioned; and an intermediate medium interlayer, arranged between the top surface and a bottom surface and used for cooperatively working together with the periodic array unit so as to attenuate electromagnetic waves radiated by an antenna. By utilizing the wave absorbing device disclosed by the present invention, wave absorption can be carried out within the preset frequency band. By the cooperating with the array unit, the purpose of attenuating the electromagnetic wave radiated by the antenna can be achieved. Even if a radiation index of the antenna is high, electromagnetic wave radiation to a human body can be reduced under the condition of not influencing communication, and the user experience is improved.</p> |
