This article presents a novel microstrip patch sensor featuring four rectangular rings represented by single complementary split-ring resonance (SC-SRR) to calculate the complex permittivity of saline solutions within the range of 0 ppt to 100 ppt. T...
Terahertz and sub-terahertz links offer wide bandwidths for future wireless communication, but practical deployment is limited by high propagation loss, atmospheric absorption, and sensitivity to blockage in non-line-of-sight environments. Here, we d...
Terahertz reconfigurable reflectarray antennas (RRAs) hold significant promise for next-generation wireless communication systems by enabling dynamic beam control to mitigate severe path loss at high frequencies. This work presents a Complementary Me...
In this work, a miniaturized and highly sensitive microwave sensor based on a complementary split-ring resonator (CSRR) is proposed for the detection of liquid materials. The modeled sensor was designed based on the CSRR structure with triple rings (...
This paper presents a compact quad-band substrate integrated waveguide (SIW) bandpass filter employing two interdigital-loaded co-directional complementary split-ring resonators (ILCD-CSRRs). Owing to the interdigital loading, each ILCD-CSRR exhibits...
