Observing and interpreting superluminal behaviors in microwave and optical experiments

Abstract

Some typical cases of tunneling and near‐field propagation experiments, carried out mainly in the microwave, but also in the optical range, giving rise to superluminal behavior, are re‐examined. The several types of superluminal behavior are classified and an attempt is made searching for a unified interpretation. Within this context, the role played by the “weak measurement” theory is also evidenced.
