Special Issue Information

Dear colleagues,

Metamaterials are artificial materials designed to realize properties unprecedented in the nature, such as negative refractive index, hyperbolic dispersions, and topological protections. These novel material properties enabled many important applications, including invisibility cloaks, super-resolution imaging, and nonreciprocal wave transports. Metamaterials were first developed based on electromagnetic resonating elements for the modulation of optical properties in order to achieve a negative permittivity and permeability for the manipulation of light. The concept was applied to acoustic resonators to develop metamaterials with a negative density and bulk modulus to modulate airborne sound. Since then, different types of metamaterials have been developed to realize a broad scope of functionalities. The recent advances in topological physics induce a new type of metamaterials with topologically protected properties and robust one-way wave transport. In optics, metamaterials made from metal and dielectric materials have been fabricated on chips, known as metasurfaces, to achieve super-thin optical lens, skin cloaking, and special optical mode emissions. More recently, acoustic metamaterials have been adapted onto microfluidic devices on-chip to manipulate surface acoustic waves that drive the motions of micro-particles and cells in acoustofluidics. These on-chip metamaterials can potentially be applied to control the photon and phonon propagations, and electron motions as well. In this Special Issue, we will cover the recent progresses in on-chip metamaterials including the physics, engineering, and their applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
