AB  - Development of energy-efficient on-demand magnonic nanochannels (MNCs) can 
      revolutionize on-chip data communication and processing. We have developed a 
      dynamic MNC array by periodically tailoring perpendicular magnetic anisotropy 
      using the electric field. Brillouin light scattering spectroscopy is used to 
      probe the spin wave (SW) dispersion of MNCs formed by applying a static electric 
      field at the CoFeB/MgO interface through the one-dimensional stripe-like array of 
      indium tin oxide electrodes placed on top of Ta/CoFeB/MgO/Al(2)O(3) 
      heterostructures. Magnonic bands, consisting of two SW frequency modes, appear 
      with a bandgap under the application of moderate gate voltage, which can be 
      switched off by withdrawing the voltage. The experimental results are reproduced 
      by plane wave method-based numerical calculations, and simulated SW mode profiles 
      show propagating SWs through nanochannels with different magnetic properties. The 
      anticrossing between these two modes gives rise to the observed magnonic bandgap.
