Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Retrieving tropospheric refractivity structure using interferometry of aircraft radio transmissions [PDF]

Atmospheric Measurement Techniques
Detailed measurements of atmospheric humidity in the lower atmosphere are currently difficult and expensive to obtain. For this reason, there is interest in the development of low-cost, high-volume opportunistic technologies to acquire measurements of ...

Meteorological interpretation of near-surface refractivity measurements

, 1999
Measurements of the radio refractive index (or refractivity) of near-surface air using phase information from radar ground echoes can be used to provide valuable humidity information on storm-scale anomalies not adequately resolved by the surface ...

Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

A theoretical estimate of relative contribution of refractivity towards group delay [PDF]

, 1991
26-28Water vapour presumably plays an important role in controlling the propagation parameters. Out of the parameters, group delay depends on refractivity and, in turn, depends on water vapour pressure. The study of extent of dominance of water vapour on

Transparent Perovskite Light‐Emitting Diodes with Conductive Oxide Top Electrodes

Advanced Materials, EarlyView.
Transparent perovskite light‐emitting diodes (TrPeLEDs) enable simultaneous display and transparency, expanding application possibilities. Using a metal oxide buffer layer and pulsed laser deposition, TrPeLEDs with diverse compositions and architectures are demonstrated.

Refractivity Statistics For Two Countries In The Middle East [PDF]

, 1989
This paper presents and compares the results of refractive index studies for Mersa Matrouh, Egypt, and Doha, Qatar. Statistics for surface refractivity and refractivity gradients at different heights from the surface are computed.
