Benchmarking Regridding Libraries Used in Earth System Modelling
Mathematical and Computational Applications, 2022 Components of Earth system models (ESMs) usually use different numerical grids because of the different environments they represent. Therefore, a coupling field sent by a source model has to be regridded to be used by a target model.

Dual-Port RHCP Compact Antenna at 868 MHz Using a 120° Hybrid Coupler
IEEE Open Journal of Antennas and Propagation, 2023 This work presents the design of a compact dual-port circularly polarized antenna based on the new coupler topology. The antenna can radiate a right-hand circular polarization (RHCP) in two opposite directions depending on the input port. In the proposed
