We propose two methods for improving decay response times in thick polymer-network LC devices of reflect arrays for millimeter-wave phase modulation. We clarified that both fast-response and low-voltage LC driving can be achieved by heat treatment after UV exposure or UV pattern exposure. The response time was decreased to 1/10.
