Coherently coupled 2×1 vertical cavity laser arrays are shown to exhibit unchanged near-field intensity profile with unequal current injection and associated far-field beam steering. The energy ...

Recently, numerous design schemes for high-order sparse linear arrays (SLAs) have been introduced for underdetermined direction-of-arrival (DOA) estimation based on high-order cumulants, which utilize ...

Vibrational sum frequency generation (SFG) spectroscopy is capable of probing the orientation of the interfacial molecules. A conventional approach assumes that hyperpolarizability tensors governing ...
