Tailored Stereo‐Configuration of Crosslinkable Polyester‐Based Solid Polymer Electrolytes for All‐Solid‐State and Binder‐Free Li Metal Batteries

Advanced Science, EarlyView.
Variations in polymer conformations of unsaturated poly(n‐alkyl esters) driven by monomer‐level stereochemistry directly govern Li+ solvation structures in polymer host matrices. The synergistic strategies of polymer conformation control, UV‐induced interchain crosslinking, and end‐group fluorination are implemented for engineering advanced solid ...

Polysiloxane‐Based Single‐Ion Conducting Polymer Electrolyte for Sodium Batteries

Advanced Science, EarlyView.
We report a polysiloxane‐based single‐ion conducting polymer electrolyte for sodium batteries. This polymer electrolyte exhibits high Na+ ion mobility and a wide electrochemical stability window, enabling the long‐term stable cycling of various cathode chemistries – also at room temperature, elevated dis‐/charge rates and active material mass loadings,

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Resonant Frequency Stability of the Dielectric Resonator on a Dielectric Substrate

IEEE Transactions on Microwave Theory and Techniques, 1981
A simple approximate method for predicting the resonant frequencies of TE modes of dielectric resonators is developed. By using this method, an analytical expression is derived for the resonant frequency stability of the dielectric resonator on a dielectric substrate, and the effect of the substrate on the stability is studied.

Temperature sensitivity of dielectric resonators and dielectric resonator oscillators

Proceedings of the 42nd Annual Frequency Control Symposium, 1988., 2003
Experiments were performed on L-band and S-band dielectric resonators (DRs) and direct-resonator-based oscillators (DROs) to investigate the details of their behavior with variation in temperature. Measurements were performed using commercially available Zr/Sn titanate and barium tetratitanate dielectric resonator materials enclosed in metal cavities ...

Resonances of a "Pillbox" Dielectric Resonator

1978 8th European Microwave Conference, 1978
Resonant frequency, quality factor and field plots are discussed for a circular-cylindrical dielectric resonator. These quantities are calculated in the limit ?r ??. The method is a perturbation technique based on an expansion in the (small) parameter (1/??r).

The influence of the dielectric constant in dielectric resonator antennas

2016 International Conference on Communications (COMM), 2016
This paper presents a comparison between dielectric resonator antennas with different dielectric constant parameter of the resonator. The antenna is fed with microstrip line. The dielectric resonators have cylindrical geometry. In HFSS software program, the simulations are up to compare the antennas' behavior as a function of different parameters, such
