An elevation and azimuth direction-finding (DF) method is presented by introducing the pattern reconfigurable antenna (PRA) into a two-element array. An equivalent multidimensional array is built by ...

A longstanding mystery of the periodic table involves a group of unique elements called lanthanides. Also known as rare earth elements, or REEs, these silvery-white metals are challenging to ...

We present a technique for designing the angle-sensing infrared detectors with subwavelength dimensions. The proposed detector is composed of a two-element long-wave infrared (LWIR) biomimetic antenna ...
