Over the past years, broadband achromatic metalenses have been intensively studied due
to their great potential for applications in consumer and industry products. Even though …

A single-step printable platform for ultraviolet (UV) metasurfaces is introduced to overcome
both the scarcity of low-loss UV materials and manufacturing limitations of high cost and low …

Metamaterials enable precise tailoring of light–matter interactions at the subwavelength
scale, permitting access to the full range of electromagnetic responses encoded in Maxwell's …

Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour.
Under uniaxial compression (tension), these materials and structures contract (expand) …

There is an increasing need to remotely monitor people in daily life using radio-frequency
probe signals. However, conventional systems can hardly be deployed in real-world settings …

With the advent of femtosecond lasers in the early 1990s, ultrafast laser processing has
proven to be an imperative tool for micro/nano machining. Two-photon lithography (TPL) is …

In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …
