DESCRIPTION:Speaker: Md. Nazmul Hasan\n\nLiquid crystal is a significantly 
 cheap material used in today’s electronic device display. Using this as 
 a variable permittivity substrate will unlock many significant advances in
  the field of antenna engineering. Liquid crystal materials change permitt
 ivity under electric voltage. But it does not consume any current\, hence 
 it consumes zero power. The insertion loss of liquid crystal material is v
 ery low compared to commercially available diode-based phase shifters whic
 h suffer from poor Q factor at mmwave frequency. On the other hand\, by si
 mply changing voltage bias on-the-fly\, we can program the phased array to
  steer the beam in real-time. The variability of permittivity of liquid cr
 ystal using voltage bias will convert it into a reconfigurable phase shift
 er for the smart phased array. The liquid crystal material can be housed w
 ithin in the same commercial printed circuit board technology infrastructu
 re for the phased array.\n\nCo-sponsored by: UBC Radio Science Lab\n\nVirt

 rystal is a significantly cheap material used in today&rsquo\;s electronic

 rystal materials change permittivity under electric voltage. But it does n

 of liquid crystal material is very low compared to commercially available
