A continuum of bright and dark-pulse states in a photonic-crystal resonator

open access: yesNature Communications, 2022
A Kerr-nonlinear resonator with normal dispersion supports bright and dark pulse states. With photonic crystal ring resonators, this work demonstrates a continuum across these nonlinear states and explores the underlying mechanism.

High specificity THz metamaterial-based biosensor for label-free transcription factor detection in melanoma diagnostics

open access: yesScientific Reports, 2023
In this work, we present a promising diagnostic tool for melanoma diagnosis. With the proposed terahertz biosensor, it was possible to selectively and sensitively detect the early growth response protein 2, a transcription factor with an increased ...

A Dual-Band Dual-Polarized Base Station Antenna Array With Isolation Enhancement

open access: yesIEEE Open Journal of Antennas and Propagation, 2023
In this paper, a dual-band dual-polarized antenna with isolation enhancement is designed. The proposed antenna operates in the frequency range of 3.4–3.6 GHz and 4.8-5 GHz, where the center frequency of the high band (HB) is 1.4 times that of the ...

Frequency Dependent Specific Heat from Thermal Effusion in Spherical Geometry [PDF]

open access: yes, 2010
We present a novel method of measuring the frequency dependent specific heat at the glass transition applied to 5-polyphenyl-4-ether. The method employs thermal waves effusing radially out from the surface of a spherical thermistor that acts as both a ...

CMOS OTA-C high-frequency sinusoidal oscillators [PDF]

open access: yes, 1991
Several topology families are given to implement practical CMOS sinusoidal oscillators by using operational transconductance amplifier-capacitor (OTA-C) techniques. Design techniques are proposed taking into account the CMOS OTA's dominant nonidealities.
