Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Validity of cognitive assessments via telecommunication links

, 1998
The use of telecommunication links in health care provision is a rapidly growing field. However, there is concern that as technology advances, teleconsultation will be seen as the method of choice without adequate research as to its efficacy. Preliminary evidence suggests that cognitive assessment of adult psychiatric patients could be reliably carried
