Autor: Sakunosuke Abe, Amon Nakagawa, Yosei Shibata, Munehiro Kimura, Tadashi Akahane

Publikováno v: Applied Physics Express, Vol 17, Iss 3, p 031001 (2024)

It is essential to estimate the surface polar anchoring energy in order to discuss the interfacial orientation of ferroelectric nematic liquid crystals. In this study, we accurately estimated the twist angle of a $\pi $ -twist cell with an antiparall

Publikováno v: Crystals, Vol 14, Iss 2, p 157 (2024)

The huge dielectric constant of ferroelectric nematic liquid crystals (FNLCs) seems to bring about a difficulty of molecular alignment control in exchange for a potential device application. To obtain a satisfactory level of uniform molecular alignme

Development of Beam Steerable Reflectarray With Liquid Crystal for Both E-Plane and H-Plane

Autor: Xiaotong Li, Hiroyasu Sato, Yosei Shibata, Takahiro Ishinabe, Hideo Fujikake, Qiang Chen

Publikováno v: IEEE Access, Vol 10, Pp 26177-26185 (2022)

In this paper, a reconfigurable reflectarray (RA) with two-finger element composed of electrically biased liquid crystal (LC) at millimeter wave band is proposed. An orthogonal bias network is proposed and developed, which can result in changes in th

Flexible polymer network liquid crystals using imprinted spacers bonded by UV-curable reactive mesogen for smart window applications

Autor: Takahiro Ishinabe, Hayato Isa, Yosei Shibata, Hideo Fujikake

Publikováno v: Journal of Information Display, Vol 0, Iss 0, Pp 1-7 (2021)

We propose junction-type, vertically aligned polymer network liquid crystals using plastic substrates for flexible smart windows, in which the spacers are formed with the imprinting method and are bonded to the substrate surface by UV-curable reactiv
