  • Investigated the switching of GST between crystalline and amorphous phases.
  • Analyzed the resulting changes in nanoantenna dipole moments and radiation patterns.

    • Main Results:

    • The nanoantenna exhibits switchable dipole moments by altering GST's phase.
    • Switching enables transitions between electric (omnidirectional) and magneto-electric (directive) dipole-like radiation.
    • Demonstrated potential for creating switchable metasurfaces (absorber/reflector).

    Conclusions:

    • The proposed GST-based nanoantenna offers dynamic control over radiation characteristics.
    • Nanosecond-timescale switching via electrical or optical pulses is achievable.
    • This work paves the way for advanced tunable optical components and metasurfaces.
