1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The design of a two-terminal antenna with decreased radar cross section (RCS) characteristics and polarization variety is shown in this work. By using stair-aperture feed to excite a cylindrical silicon dielectric resonator, circular polarization is accomplished. An aperture arrangement that is mirror-oriented between terminal-1 and 2 improves isolation by 30 dB. A frequency selective surface based on a split-ring resonator (SRR) is positioned between the twin ports and around the antenna structure in order to reduce monostatic RCS (MRCS). The radiator functions between 2.45 and 3.35 THz, with a 3-dB axial ratio between 2.65 and 3.15 THz. In the operational band, the MRCS is lowered by around 30 dBsm. The suggested design is well suited for radar applications in THz regime due to its broadside radiation and advantageous diversity characteristics.
