Chipless RFID systems can be considered as a special case of passive RFID systems,
where the tag contains no power source and no electronics. Instead, the tag's information is …

In addressing sensing in harsh and dynamic environments, there are no available millimeter-
wave chipless and wireless sensors capable of continuous operation at extremely high …

In this paper, a low-profile metasurface retroreflector based on an ultra-thin wide-angle and
high-efficiency metalens is proposed and investigated. Owing to its stable high transmission …

Transformation optics (TO) or transformation acoustics (TA) theory provides an elegant
framework for designing intricate wave-material interaction devices. Combining TO or TA …

In this paper, we investigate a shortened horn antenna with high gain that is enabled by a
3D-printed gradient index (GRIN) lens composed of high permittivity zirconia. The baseline …

Using conformal transformation optics, a cylindrical shell made of an isotropic refractive
index material is designed to improve the directivity of a wire antenna while making it …

This contribution discusses the impact of sintering temperatures on dielectric properties of
3D‐printed alumina (Al2O3) in the W‐band, by evaluating high quality factor (− Q) …

Recently, many research efforts have been dedicated to improving light coupling into solar
cells and reducing optical losses. Promising candidates regarding scalability include direct …

Monitoring pathogens has become a major challenge for society and research in recent
years. Of great interest are refractive index sensors, which are based on the interaction …

Lithography‐based ceramic manufacturing (LCM) utilizes slurries with low solids loading,
which makes pressureless sintering to full density especially difficult. A further compounding …
