Gallium Nitride Phase Shifters [PDF]

, 2015
This thesis presents two different types of high-power gallium nitride (GaN) phase shifters designed for X-band (8–12 GHz) but offering good performance over a much wider band.

Birefringent achromatic phase shifters for nulling interferometry and phase coronagraphy

, 2003
Achromatic Phase Shifters are mandatory components in the field of nulling interferometry and phase coronagraphy. Indeed, in order to detect faint objects (e.g. exo-planets) around a central bright star, one must attenuate the latter by all means.

Differential RF-MEMS Enabled Power Divider-Based Phase Shifters

IEEE Access
New types of co-designed differential RF-MEMS enabled power divider-based phase shifters (PDPSs) are reported. They are based on T-junction power dividers co-integrated with single-pole $N$ -throw (SPNT) RF-MEMS switches that simultaneously control the ...

Toward the information-theoretic limit of programmable photonics [PDF]

APL Photonics
The scalability of many programmable photonic circuits is limited by the 2π tuning range needed for the constituent phase shifters. To address this problem, we introduce the concept of a phase-efficient circuit architecture, where the average phase shift

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Microwave phase shifters based on sol-gel derived Ba0.3Sr0.7TiO3 ferroelectric thin films

In this paper, we report on the performance of microwave phase shifters implemented on sol-gel derived Ba0.3Sr0.7TiO3 (BST) thin films. Coplanar waveguide (CPW) phase shifters, loaded-line phase shifters, and reflection-type digital phase shifters; have ...
