Advanced Photonics Research, Volume 7, Issue 7, July 2026.An ENZ metamaterial slab enables near‐field coupling suppression in dual circularly polarized stacked patch antennas while preserving radiation performance. The near‐zero‐index environment attenuates the transmission of parasitic coupling components between adjacent radiators, distinct from conventional current‐cancelation or port‐compensation ...

Geophysical Prospecting, Volume 74, Issue 6, July 2026.ABSTRACT A conjugate operator pair is introduced for wave‐equation Kirchhoff modelling and migration, formulated as time‐space partial differential equations. The operator pair allows for iterative linearized waveform inversion and supports the reconstruction of angle‐dependent reflectivity images. The proposed forward modelling operator represents the
