MEMS‐Based Magnetoelectric Antennas for Wireless Power Transmission in Brain‐Implantable Devices

Advanced Materials Technologies, EarlyView.
Magnetoelectric (ME) antennas allow the minimization of the invasiveness of brain implantable devices, via powering wirelessly systems able to actuate neural tissue. In order to achieve the necessary power efficiency transmission, the choice of the materials and the system assembly is vital.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

Advanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

The role of body rotation in mathematical models of isotropic plastic behaviour

Applied Mathematical Modelling, 1979
A mathematical model of plastic behaviour which takes into account the effect of rotation of material line elements is proposed. The model is used to calculate the rotation of principal axes of strain increment during nonradial loading. The values of rotation so obtained are compared with the values predicted by Mises theory and the modified theory of ...

Directionally Asymmetric Holographic Imaging for Arbitrary Polarization States Using Janus Metasurfaces

Advanced Optical Materials, EarlyView.
We demonstrate single‐layer titanium dioxide Janus metasurface holograms that achieve directionally asymmetric imaging under forward and backward illumination. By integrating the Dammann grating principle with precise phase control, our design produces high‐fidelity holographic images for arbitrary polarization states at 532 nm, simplifying fabrication,
