To study a low-frequency electromagnetic device represented by a finite-element (FE) model coupled with a complex electrical circuit, an approach based on the co-simulation principle can be ...

In response to this challenge, this paper proposes employing orthogonal time-frequency space (OTFS) modulation for SR systems in hostile environments. By processing signals in the delay-Doppler (DD) ...

In this study, an ion-funnel-integrated photoionization (IFPI) source was developed. Following a systematic investigation of the effects of radio frequency (RF) amplitude on the ion transmission ...
