Varactor tuned ring resonatormicrowave oscillator

Electronics Letters, 1996
A varactor tuned X-band microwave oscillator using a ring resonator side coupled to a microstrip line is presented. The tuning range of the oscillator is linear and the circuit is implemented using planar processing technology. It can also easily be implemented at millimeter wavelengths. The design guidelines are presented.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Microwave Oscillator Design for a SRR Based Biosensor Platform

Proceedings, 2018
A sensor for biomedical markers based on a split ring microwave resonator (SRR) was developed. The surface of the microwave resonator is covered with receptors that specifically bind to the target proteins where the local permittivity is changed.

Gigahertz voltage-controlled ring oscillator

Electronics Letters, 1986
Designs for ring oscillators that provide a 2:1 range of voltage-controllable frequency are compared. Simulated results are given for a ring oscillator intended for a 1 ?m NMOS monolithic IC implementation. The circuit displays a variable frequency from 1.5 GHz to 2.5 GHz, and requires no off-chip tuning elements.

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

Advanced Materials, EarlyView.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).
