Dynamic cloaking of a diamond-shaped hole in elastic plate
Invisibility cloaks for flexural waves have been mostly examined in the continuous-wave regime, while invisibility is likely to deteriorate for short pulses. Here, we propose the practical…

On the investigation of two non-neutral static bodies
In this work, we have considered statics of two non-neutral bodies unaffected by external force fields. We have tried to calculate the value of θ at which net field strength becomes zero however…
