Special Issue Information

Dear Colleagues,

Metamaterial-inspired structures exhibit a high-quality factor and a small-form factor which provide favorable opportunities to conceive a diverse range of sensing applications. New paradigms are shifting towards flexible and stretchable structures owing to their great potential in various fields. Electromagnetic waves (microwave–millimeter regime) have the potential to cross the capacitive barrier of cell–membrane and peep into the cytoplasm. There is a great need to design metamaterial-inspired physical–biochemical sensors which, whilst safer than conventional ultrasound techniques, could be an inexpensive and non-invasive sensing platform with a small-form factor. Prominently, the selectivity of microwave/RF biochemical sensors suffers compared to the selectivity of electrochemical/optical sensors; however, new techniques can be invented to complement it.

This Special Issue is dedicated to metamaterial-inspired sensors, including but not limited to conventional fabrication techniques/substrates. Flexible sensing platforms made from a combination of soft electronics and metamaterial-inspired structures would have high priority. For instance, a metamaterial-inspired epidermal biosensor as a diagnostic and therapeutic tool can be envisaged. In general, metamaterial-inspired sensors have found numerous applications, such as chemical sensors, strain sensors, pressure and temperature sensors, and crack detection and tactile sensors.

In this paper, we propose a bi-directional loop antenna array using magic cube origami. The proposed antenna array consists of three one-wavelength loop antenna elements with series feeding. Each loop antenna is realized on a single magic cube, and three cubes are connected in series to form the array. The three cubes can be easily folded and unfolded due to being constructed in the form of a magic cube origami. Antenna volume can be minimized for high mobility by folding the array, which radiates a bi-directional pattern with full volume when unfolded. The proposed antenna was designed at 1.39 GHz. When the single antenna is realized on the single cube, the peak gain is 4.03 dBi. The peak gain increased to 5.2 and 5.53 dBi with two and three antennas, respectively. Half-power beam width (HPBW) with three antenna elements decreased to 40° from 360° compared to the HPBW with the single antenna. The proposed antenna performance was assessed numerically and experimentally. Full article
