The flexible and conformal interconnects for electronic systems as a potential signal transmission device have great prospects in body-worn or wearable applications. High-efficiency wave propagation structure deformation around human body at radio communication are still confronted with huge challenges due to the lack of methods control achieve deformable simultaneously. Here, inspired by kirigami technology, new paradigm construct spoof plasmonic (SPIs) that support radiofrequency (RF)...
Abstract Mechanically controlled reconfigurable electromagnetic metamaterials that can dynamically modulate their properties by simple mechanical compression/stretch hold great potential in wavefront control, tunable filtering, and holographic display. Undesired operating frequency shift difficult independent controlling of unit cells existing mechanically greatly limit wide developments.

This work reveals the nonlocal effect twisted electric dipoles demonstrates its capability non‐volatile transformation on scattering. When rotated to form a tilted array, dipolar resonances yield interactions tuned by rotation angle.

The metasurface has recently emerged as a powerful platform to engineer wave packets of free electron radiation at the mesoscale. Here, we propose that Airy beams can be generated when moving electrons interact with bianisotropic metasurfaces. By changing intrinsic coupling strength, full amplitude coverage and 0-to-π phase switching Smith-Purcell realized from meta-atoms. This unusual property shifts front assembled beam toward parabolic trajectory. Experimental implementation displays...
With the increase of system complexity in wireless communications, higher requirements on miniaturization and integration are put forward for future antennas. Antennas different frequency bands need to be placed together achieve multiple communication goals. However, when a large-sized antenna operating at low-band (LB) is used alongside small-sized high-band (HB), radiation from former can block latter, thereby impacting overall functioning system. In this work, we propose novel method...
Abstract Metallic nanoshells have emerged as promising optical cavities to steer hybridized plasmonic resonances that show the high spectral tunability and a large surface area of localized fields.

Tunable three-dimensional (3D) electromagnetic (EM) metasurfaces are critical for dynamic modulation of EM responses but their construction and tuning mechanism still complex. Here, we report a simple yet effective 3D reconfigurable metasurface, which was obtained from planar kirigami polyimide substrate printed with periodically arranged copper split-ring resonator. Under mechanical stretch, the two-dimensional (2D) metasurface can be uniformly deformed into state, is its transmission...
Abstract Tunable three-dimensional (3D) electromagnetic metasurfaces are essential for achieving selective modulation of polarized waves, but they usually require complex designs and the use smart materials, posing great implementation challenges.
