Abstract

fetched live from OpenAlex

Abstract Dielectric media affect the wave propagation by their reflective index. Their use in antennas can provide a number of diverse benefits. In applications such as high‐gain antennas, they influence the phase of the propagating waves, and thus influence the direction and gain of the transmitted waves. Lens antennas are typical examples that can be used alone, or in conjunction with other antennas, such as horn and microstrip antennas, to enhance their gain. In other applications like dielectric loaded horns and waveguides the use of dielectric inside them controls the excitation of various modes and thus the performance of the horns. Hybrid and multimode horns are examples that can improve the horn performance for reflector feed applications. Similarly, dielectric resonator antennas can control and improve the radiation performance by controlling the excitation and the phase of the wave propagating through them. Dielectrics being non‐conducting can also be used to insulate and, thus, isolate the antennas from living tissues, in medical treatment and studies. Large permittivity of some dielectrics reduces the signal wavelength and in areas of small antennas can be used to reduce the antenna dimensions. Finally, the dielectric permittivity also influences the wave impedance and can be used to match the impedance of antennas to the radiation media and enhance their gain. This article provides a brief review of some of these applications.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
