Differently distorted areas on a polycarbonate sample are studied by means of Raman spectroscopy. The various Raman lines, whose energy shifts range between 200 and 3200 cm-1, are compared for different sample positions with respect to…
Near-field sensing with extremely large-scale antenna arrays (ELAAs) in practical 6G systems is expected to operate over broad bandwidths, where delay, Doppler, and spatial effects become tightly coupled across frequency. The purpose of…
We used broad-band diamond-shape antennas, whose bandwidth could cover the frequency range between the pump laser and the scattered modes, in conjunction with uniformly deposited graphene test films.
Graphene nanoribbons (GNRs) have attracted considerable interest as their atomically tunable structure makes them promising candidates for future electronic devices. However, obtaining detailed information about the length of GNRs has been…
