Title (EN) LIQUID-CRYSTALLINE MEDIUM
(FR) MILIEU CRISTALLIN LIQUIDE
Abstract:
(EN) The present invention relates to liquid-crystalline media comprising one or more compounds of formula DFS, in which the groups and parameters occurring have the meanings indicated in claim 1, to high-frequency components comprising same, especially microwave components for high-frequency devices, such as devices for shifting the phase of microwaves, in particular for microwave phased-array antennas. The present invention further relates to novel mesogenic compounds.
(FR) La présente invention concerne des milieux cristallins liquides comprenant un ou plusieurs composés de formule DFS, dans lesquels les groupes et les paramètres se produisant ont les significations indiquées dans la revendication 1, des composants haute fréquence comprenant ceux-ci, en particulier des composants micro-ondes pour des dispositifs à haute fréquence, tels que des dispositifs pour décaler la phase de micro-ondes, en particulier pour des antennes réseau à commande de phase à micro-ondes. La présente invention concerne en outre de nouveaux polymères mésogènes.
