Drastic declines in insect populations are a vital concern worldwide. Despite widespread
insect monitoring, the significant gaps in the literature must be addressed. Future monitoring …

Harmonic Radio Frequency Identification (RFID) systems have attracted significant interest
over the last decade as it provides many benefits over the conventional RFID systems …

It all started with a spark. Let us rewind back to 1887, in Germany. The days were getting
cooler in the garden of the Technische Hochschule in Karlsruhe as Heinrich Rudolf Hertz …

This paper presents a novel passive Schottky-diode frequency doubler equipped with an on-
off keying (OOK) modulation port to be used in harmonic transponders for both identification …

The article presents a novel design of a compact wearable harmonic transponder with
double-plane symmetry, composed of a dual-band patch-type antenna loaded by an HSMS …

This paper presents a holistic and authoritative review of the role of microwave technologies
in enabling a new generation of wearable devices. A human-centric Internet of Things (IoT) …

We present two frequency modulated continuous wave (FMCW) harmonic radar prototypes
for application in insect tracking. They respectively operate in the maritime radar allocations …

This awork presents a novel single layer dual-band meander-line harmonic tag antenna
implemented on a thin flexible substrate. The proposed prototype consists of folded …

A new approach to exploit nonlinear reradiation of electronic circuits under test (ECUT) for
classification of electronic devices using harmonic radar is proposed in this article. Unlike …

A broad review of publications relevant to nonlinear radar is conducted. The principle-of-
operation of nonlinear radar is summarized and applications for this technology are listed …
