A Super‐Ionic Solid‐State Block Copolymer Electrolyte

Small, Volume 20, Issue 49, December 5, 2024.
The super‐stoichiometric addition of LiTFSI to poly(ethylene oxide) block copolymers leads to super‐ionic solid polymer electrolyte membranes reaching exceptionally high ion conductivities of up to 0.04 S cm−1 at room temperature, with activation energies of only 0.19 eV.

Time transfer via single‐record TDoA measurements of GNSS satellites using direct cross‐correlation and relative pilot code phases

IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2447-2453, December 2024.
A method is presented to passively synchronise data records via GNSS raw signals in a single record requiring only a GNSS antenna, an analogue‐to‐digital converter and computation hardware. The clock bias is estimated via the common view method with either full raw signal correlation or software‐based code correlation of individual signals from the GPS,

Wideband Diplexer With Narrow Channel Spacing Using Hybrid Bandpass-Bandstop Structures

IEEE Access, 2020
In this paper, a wideband diplexer with narrow channel spacing is designed by using hybrid bandpass-bandstop structures. Two wideband bandpass structures are designed with the transmission zeros at the upper or lower passband edges to achieve high skirt ...

Microstrip diplexers with dual-mode patch resonant junctions [PDF]

, 2017
A conventional diplexer is made up of two channel filters which are connected to a transmission-line based signal distribution network. In this work, a novel diplexer has been proposed and designed using hairpin resonator filters that are joined together

Integrating deep convolutional surrogate solvers and particle swarm optimization for efficient inverse design of plasmonic patch nanoantennas

Nanophotonics, Volume 13, Issue 21, Page 3963-3983, September 2024.
Abstract Plasmonic nanoantennas with suitable far‐field characteristics are of huge interest for utilization in optical wireless links, inter‐/intrachip communications, LiDARs, and photonic integrated circuits due to their exceptional modal confinement. Despite its success in shaping robust antenna design theories in radio frequency and millimeter‐wave

FM/CW radar system [PDF]

, 1978
An FM/CW radar system is presented with improved noise discrimination in which the received signal is multiplied by a sample of the transmitted signal, and the product signal is employed to deflect a laser beam as a function of frequency. The position of
