Researchers have designed and demonstrated stretchable waveguides that maintain efficient, stable signal transmission of ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.

Abstract: This letter presents a dual-mode substrate-integrated waveguide (SIW) operating in the D band (110–170GHz). The structure is fabricated using standard CMOS-compatible nanofabrication ...

Abstract: In this work, a design scheme for a tunable waveguide phase shifter is proposed, which utilizes anisotropic artificial electromagnetic materials (AEMs). The configuration scheme consists of ...

Grounding exercises help you refocus on the present to relieve feelings of anxiety, stress, depression, or PTSD. Physical grounding techniques use your five senses to help you move through distress by ...

Taking part in a structured exercise program after adjuvant therapy reduced the risk of colon cancer recurrence by 28% in a phase 3 trial — highlighting a powerful strategy for improving recovery and ...
