A tunable ultra-wideband metamaterial absorber based on graphene is presented herein. Its absorption exceeds 90% from 1.57 to 8.46 GHz when the Fermi level of the graphene is 0.7 eV, and it can be tuned by changing the bias voltage applied on the gra
Based on PIN diode and resistive film, a dual/single wideband switchable metamaterial absorber at low frequency is presented in this paper. Its absorption is over 90% from 0.8GHz to 1.5GHz and from 4.2GHz to 5.2GHz while the PIN diode operates in for

Rapid test (RT) is the principal screening method in the HIV control practice. However, this method may lead to inaccurate detection, primarily due to the more than 4 weeks of window phase. In the present study, we performed a HIV DNA screening metho
