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,

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

Low‐loss compact diplexer based on complementary spiral resonators

Microwave and Optical Technology Letters, Volume 66, Issue 6, June 2024.
Abstract The article describes a novel low‐loss microwave diplexer based on compact planar filtering elements. These are composed of spiral resonators and etched directly onto the signal layer. Furthermore, their design and optimization prove to be easy, and their native high‐pass/low‐pass characteristics are perfectly suited for assembling a diplexer.
