RF Phase Shifters for Phased Arrays

, 2011
Phase shifters are essential components in a phased array for adjusting the phase of each antenna path and steering the beam. There are various types of conventional RF phase shifters, and they are analyzed in detail in this chapter.

E-Band Low-Loss Reconfigurable Phase Shifters

, 2023
Two types of low-loss mechanically reconfigurable phase shifters at E-band based on gap waveguide (GW) technology, the GW slow wave and the GW width-variation, are proposed in this letter. Phase shifts are achieved by mechanical movements.

Clearing a path for light through non-Hermitian media

Nanophotonics
The performance of all active photonic devices today is greatly limited by loss. Here, we show that one can engineer a low loss path in a metal-clad lossy multi-mode waveguide while simultaneously achieving high-performance active photonic devices.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
