Advanced Functional Materials, EarlyView.Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Conversion between dipoles with different spatial parities by circularly polarized light
Materials Today QuantumWe investigate the effect of a circularly polarized light on multipoles based on the Floquet formalism. We show that the irradiation of the circularly polarized light converts the spatial parity of dipoles at the microscopic level; the electric (magnetic

Circularly polarized light detection using chiral hybrid perovskite
Nature Communications, 2019 Optics-free circularly-polarized light detection has suffered from extremely low responsivity. Here Chen et al. demonstrate chiral organic–inorganic hybrid perovskite based detectors to distinguish circularly-polarized light with high responsivity of 797

Phonon-driven spin-Floquet magneto-valleytronics in MoS2
Nature Communications, 2018 In 2H semiconducting transition-metal dichalcogenides the valley-selective excitation has been achieved with circularly polarized photons. Here, the authors show that circularly polarized phonons produce a valley-dependent dynamic spin state as a result ...

Circularly Polarized Patch Array Antenna Fed by Microstrip Line
, 2007 由於可以降低多重路徑反射和干擾，圓極化的技術被廣泛的應用於微米波頻段。微帶天線也因為它的輕薄、短小、架構簡單和易於與其他電路結合的優點而被大家所熟知。但是，微帶天線有一個不被大家所喜愛的缺點，就是它的頻寬非常的窄，這個缺點同時也嚴重地限制了微帶天線的應用。 爲了要克服微帶天線的窄頻的缺點，吾人採用了循序旋轉的饋入技術，這個技術不但改進了微帶天線的阻抗頻寬，同時也增加了它的圓極化頻寬。 在這篇論文中，幾種利用了循序旋轉饋入技術的圓極化微帶陣列天線被提出 ...
