In this article, a wideband energy selective surface (ESS) with quasi-elliptic response and high shielding effectiveness is proposed for providing out-of-band rejection high-power microwave protection at the same time systems. By cascading three layers of structures loading diodes, nonlinear transmission property are realized.

As a potential risk to human and environmental health, radio frequency (RF) radiation should be studied due the higher frequencies larger bandwidths that may employed. Electromagnetic interference (EMI) shielding materials can prevent exposure RF radiation, but most of them are visibly opaque. In this work, we propose fabricate transparent EMI using an ultrathin silver layer sandwiched by oxides (SLSO) as building blocks. The samples with double-sided SLSO (D-SLSO) structure exhibit highest...

Is sucrose more effective than trehalose in human ovarian tissue cryopreservation? The effect of as a cryoprotective agent (CPA) was not significantly different from that cryopreservation. Sugars have the ability to keep cell membrane intact and can decrease toxicity CPAs. Sucrose is most commonly used non-permeable CPA, while rarely Although various methods are utilized evaluate efficiency cryopreservation, few studies evaluated cryopreservation viewpoint biomechanics. A total 15 samples...
