The implementation of wideband 90° hybrids on non‐optimal substrates
Electronics Letters, 2022 A new technique to implement wideband 90° hybrid coupling profiles on non‐optimal substrate configurations is presented. The technique uses an impedance taper over the whole length of the hybrid to remove the restriction of a substrate defined maximum ...

Magnetic Nature of Light Transmission through a 5-nm Gap
Scientific Reports, 2018 Slot antennas have been exploited as important building blocks of optical magnetism because their radiations are invoked by the magnetic fields along the axes, as vectorial Babinet principle predicts.
