      liquid-crystal cell.

AB  - We observe a new feature ( plateau), sandwiched between two exponentially 
      decaying components, in the switching response of a polymer-dispersed 
      liquid-crystal (PDLC) cell. Upon application of square-wave electrical pulses, 
      the cell response exhibits a complex decay whose characteristics are 
      significantly different within and outside the applied field. We interpret these 
      results in terms of reorientation dynamics of nonspherical droplets in the PDLC. 
      Irradiation of the PDLC with gamma rays induces significant changes in the cell 
      response in a manner that is consistent with redistribution of charges at the 
      liquid-crystal-polymer interface in the PDLC.
