Special Issue Information

Dear Colleagues,

In recent years, phononic crystals and elastic metamaterials have provided new opportunities for wave control and a wealth of applications have been proposed in acoustics and vibration control. In parallel, the development of elastic metamaterials has also lead to lightweight microstructured designs exhibiting exceptional quasistatic mechanical properties.

However, no universally valid criteria exist for the design of efficient metamaterial structures, both in the quasistatic and the dynamic domains. A promising new approach in the development of advanced architectures for new materials consists in drawing inspiration from Nature, which has developed complex designs with advanced properties and functionalities through evolution, over thousands or millions of years.

Bioinspiration has already enabled the design of structures with optimized mechanical properties such as strength or toughness. Since metamaterials derive their unconventional behaviour from structure rather than from material properties, biological systems are ideal candidates as a source of inspiration.

This Special Issues welcomes contributions related to the mechanics of Bioinspired metamaterials, both for the control of wave propagation and for the achievement of unconventional quasistatic properties, at various size scales and in various engineering fields. Submissions are expected related to investigations on analytical and numerical approaches for novel optimized bioinspired designs, as well as their fabrication and experimental verification.

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 submissions that pass pre-check are 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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.

In this article, a compact dual band metamaterial inspired circular microstrip patch antenna for WLAN applications is presented. The antenna consists of a circular patch loaded with a complementary double negative metamaterial structure which produces a percentage miniaturisation of 60.7%. The circular microstrip patch antenna used for developing the proposed antenna has a resonant frequency of 6.2 GHz with an impedance bandwidth of 3.5% before the metamaterial structure is applied upon it. The loading of the proposed metamaterial structure inspires the antenna to lower its resonant frequency with enhanced bandwidth and generate one additional resonance. The designed antenna can be tuned throughout the C-band by simply altering the size of the metamaterial structure loaded upon it. However, the prototype of the antenna is designed for the most commonly used wireless communication bands at 2.4 GHz and 5.2 GHz. The 10 dB impedance bandwidth of 1.63% at 2.4 GHz and 13.15% at 5.2 GHz are achieved by this design. The electrical parameters of the proposed antenna are ka = 0.72 and QChu = 4.07 rendering it electrically small. This electrical compactness and bandwidth enhancement are caused by the loading of metamaterial structure. The proposed antenna is fabricated on low cost FR4 substrate and has an overall compact electrical size of 0.164 λ0 × 0.164 λ0 × 0.013 λ0 and physical dimensions 20 × 20 × 1.6 mm3, with peak gain 3.8 dBi and 2.9 dBi at 2.4 GHz and 5.2 GHz respectively.
