Active Gain-Controlled Beam-Steering Transmissive Surface

IEEE Open Journal of Antennas and Propagation
Engineered electromagnetic surfaces enable enhancing the strength of a signal in the desired direction(s) using anomalous reflection/transmission. However, to boost the gain of the conventional surfaces, the common solution is to increase its aperture ...

The MIMO-OTFS Technique in the Next 6G Communications

Engineering Access
The orthogonal time-frequency space (OTFS) technique is a promising method of waveform modulation that encodes data in the delay-doppler (DD) domain. OTFS distinguishes itself from conventional multiplexing methods by employing two-dimensional modulation

Study of excitation transfer in laser dye mixtures by direct measurement of fluorescence lifetime [PDF]

By directly measuring the donor fluorescence lifetime as a function of acceptor concentration in the laser dye mixture Rhodamine 6G-Cresyl violet, we found that the Stern-Volmer relation is obeyed, from which the rate of excitation transfer is determined.
