Planar Microwave Resonant Sensors: A Review and Recent Developments

Applied Sciences, 2020
Microwave sensors based on electrically small planar resonant elements are reviewed in this paper. By virtue of the high sensitivity of such resonators to the properties of their surrounding medium, particularly the dielectric constant and the loss ...

Design of planar waveguide directional couplers with arbitrary modal electric field

IET Optoelectronics, 2022
The purpose of this work is to present a method for designing planar waveguide couplers of arbitrary modal electric field distributions. The idea here is to create couplers with unusual electric fields, which confine in one planar waveguide.

Planar (Bio)Sensors for Critical Care Diagnostics [PDF]

Clinical Chemistry, 1997
Advances in planar (bio)sensors have allowed whole-blood diagnostics to be applied in testing close to the patient, resulting in rapid turnaround times, which are especially desirable in critical care settings. Several new technologies and custom chemicals had to be integrated to allow high performance, small sample size, fast response time, and cost ...

Excitation of Surface Plasmons Using Tilted Planar-Waveguide Bragg Gratings

IEEE Photonics Journal, 2011
We present a planar-integrated optical surface plasmon refractometer. The fabricated device operates by grating-matched coupling between a core waveguide mode and a set of hybrid plasmon-dielectric modes of a much wider integrated structure.

A Bragg grating sensor for detection of monolayers at a surface [PDF]

, 2009
Planar waveguides can be written with a UV-laser into photosensitized silica to produce a wide range of optical devices. Careful modulation of two interfering beams allows Bragg gratings to be directly written into the channel (Figure 1.a).

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Frontside-micromachined planar piezoresistive vibration sensor: Evaluating performance in the low frequency test range

AIP Advances, 2014
Using a surface piezoresistor diffusion method and front-side only micromachining process, a planar piezoresistive vibration sensor was successfully developed with a simple structure, lower processing cost and fewer packaging difficulties.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
