The system presented in Figure 1 is composed of an epoxy–water–epoxy triple layer immersed in water. The layers are supposed infinite in the 𝑥1x1 and 𝑥2x2 directions. Here, we consider the propagation of acoustic waves polarized in the sagittal plane (𝑥1x1, 𝑥3x3) defined by the...
A circularly polarized wearable antenna that operates at 5.8 GHz is proposed on a polydimethylsiloxane (PDMS) substrate [39]. Highly conformal characteristics, lightweight, and a good mechanical stability of the substrate make it a good choice for a wearable antenna design. The comparison of ...
A polarized bifocal switch based on liquid crystals operated electrically and opticallyAbhishek SrivastavaChen, H. S. et al. A polarized bifocal switch based on liquid crystals operated electrically and optically. J Appl Phys. 117, 044502 (2015)....
In its de-energized state, the crystal will not affect polarized light. But when an electric field is applied across the crystal, the plane of polarization of the incident light is rotated by 90º, allowing it to pass the second crossed polar- izer. This completes the optical cavity and...
All molecules havekineticenergy; they are vibrating. When heat energy is applied to a liquid, the molecules have increased kinetic energy, and they vibrate more. If they vibrate enough, they bump into each other. The disruptive force of molecules bumping into each other allows them to overcome...
With the advance of smart material science, robotics is evolving from rigid robots to soft robots. Compared to rigid robots, soft robots can safely interact with the environment, easily navigate in unstructured fields, and be minimized to operate in narr
(z=1,3,…,N)are assumed to be polarized in the radial direction and electrically connected in the preferred parallel configuration in order to make full use of the actuation voltage8,59,61,65,66. Also, the rheological properties of SVE core layers(z=2,4,…,N−1)can be reversibly ...
The 3D electron microscope can view the detected object 360 degrees, the image is clear and smooth, and there will be no problems such as smearing. The device uses a 2 million high-speed HDMI camera to transmit images in real time, and adds a self-developed image processing algorithm, so...
46,47 achieved a 2D/3D switchable integral imaging display based on a polarized liquid crystal micro lens array. By controlling the polarization direction of the light, the effect of 2D/3D switching was achieved. H. Deng et al.48 also used a multi-layer lens array and further improved the...
