Microwave planar sensors employ conventional passive complementary split ring
resonators (CSRR) as their sensitive region. In this work, a novel planar reflective sensor is …

A machine learning aided (MLA) method is employed for the direct permittivity retrieval of
dispersive and non-dispersive materials. The method requires low-cost measurements since …

Simple methods using a microstrip coupled-line directional coupler (CLDC) are presented
for dielectric constant measurements. The material under test (MUT) is placed on the …

A machine learning (ML) approach is proposed to provide an accurate retrieval of the
dielectric properties of materials. In our earlier work, based on a semi-analytic solution of …

A reconfigurable biosensor with different spectral sensitivities could provide new
opportunities to increase the label-free selectivity and sensitivity for biomolecules. Here, we …

Microwave resonant sensors are limited in their current form to a static resonant frequency,
which can lead to misidentification when two materials or mixtures with similar dielectric …

Microwave sensors have attracted interest as non-destructive metal crack detection (MCD)
devices due to their low cost, simple fabrication, potential miniaturization, noncontact nature …
