Dataset 01: ZIP file containing the near field radiated by the horn antenna (more precisely, the S_21 parameter, which is proportional to the measured electric field). The ZIP file has 201 *.txt files, one *.txt file per frequency (the frequency value, in MHz, is indicated on the name of each *.txt file), Dataset 02: ZIP file containing the field scattered by the targets in the imaging domain (see the image “PictureSetup.png”). The ZIP file has 201 *.txt files, one *.txt file per frequency (the frequency value, in MHz, is indicated on the name of each *.txt file), This dataset corresponds to the measurements of a monostatic microwave imaging system, collected using the facility described in [1]. The first dataset, "Escatt_meas.mat", corresponds to the field scattered by the targets shown in the picture. Two targets were considered: a 18 cm long × 14 cm diameter metallic can, and a 18 cm diameter and 4 cm thick plastic disk, placed 22 cm above the metallic floor of the facility. The size of the scattered field acquisition domain was Lx × Ly = 65 cm × 40 cm, discretized every δx,y = 10 mm (λ/2 at the center frequency of 15 GHz), and placed 1 m above the floor of the measurement facility. The Tx and Rx antennas were two Standard Gain Horn (SGH) horn antennas [2]. The second dataset, "Erad_horn.mat" is the near field radiated by the Tx and Rx Standard Gain Horn (SGH) antennas in the 12-18 GHz frequency band. The field radiated by these antennas was measured in the same 12-18 GHz frequency band, in an acquisition domain discretized also every 10 mm, placed 50 cm above the SGH aperture. The field radiated by the SGH was processed using the backward transformation algorithm described in [3] to obtain the SGH aperture fields This dataset can be processed following the methodology described in [4],[5] (modified Delay-and-Sum algorithm) and in [6] (modified Fourier-based imaging algorithm).

This dataset corresponds to the near field (NF) measurements of a 70 cm diameter offset reflector antenna, fed with a circularly polarized helix antenna, working at 4650 MHz [1,2]. The reflector antenna was measured at the spherical range in an anechoic chamber of the University of Oviedo, in Spain. This anechoic chamber has a roll over azimuth positioner that enables full spherical acquisions. Two different measurement distances were considered, R1 = 3.198 m and R2 = 5.191 m. Samples on both spherical acquisition surfaces were taken according to a sampling rate of 1 degree in theta (or azimuth axis), and 3 degrees in phi (roll axis). The two tangential components of the electric field (Eth, Eph) were measured. This dataset can be used for testing near-field-to-far-field (NF-FF) transformation techniques [3]. Besides, measurements are provided at two different distances, thus enabling the assessment of amplitude-only antenna diagnostics and NF-FF transformation methods [4-7].

This work presents an electrochemical platform designed for the relative quantification of the long noncoding RNA (lncRNA) CCAT1, a biomarker associated with colorectal cancer (CRC), using GAPDH mRNA as an endogenous control. The system integrates two sandwich-type genosensors that employ multiple fluorescein-labeled detection probes to enhance sensitivity by enabling the attachment of several redox enzymes per target molecule. Coupled with RT-PCR amplification, the platform successfully detected CCAT1 at clinically relevant concentrations in RNA extracted from CRC cell lines and spiked plasma samples. The ratio of signals from both sensors allows relative expression analysis, reducing variability and improving diagnostic reliability. This approach shows promise for minimally invasive CRC screening and could be adapted for other lncRNAs linked to different cancers.
