This study presents a novel design of D-band bandpass waveguide filter by incorporating dual-mode (TE102/TE201) and Singlet (TE201) cavities with higher Q-factor to reduce insertion loss. Since both ...

Shear horizontal (SH) ultrasonic guided waves can be generated by periodic permanent magnet (PPM) electromagnetic acoustic transducers (EMATs) and are attractive for non-destructive evaluation.
