Development of a Dual-Mode Electromagnet-Based EMAT With Halbach Array Configuration

Electromagnetic acoustic transducers (EMATs) enable noncontact ultrasonic inspection without couplants, but bulk-wave excitation and modal selectivity depend strongly on the bias magnetic-field distribution. This article presents a dual-mode electromagnet-based EMAT with a Halbach-type bias configuration (DMHB-EMAT) fo...

Holistic Fusion of Fragmented Signal Features for Automatic Modulation Recognition via an Adaptive Topological Network

Automatic modulation recognition (AMR) remains challenging under low-signal-to-noise ratio (SNR) conditions, where severe noise can obscure weak modulation-specific waveform patterns. To address this issue, this paper proposes an Adaptive Holistic Fusion Network (AHFN) for robust low-SNR modulation recognition. AHFN fi...
