In this communication, an orbital angular momentum (OAM) mode-reconfigurable antenna based on a uniform circular array (UCA) is presented. To realize multiple switchable operating states while ...

Non-Hermitian topological systems exhibit a range of unique phenomena that are absent in their Hermitian counterparts.

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular ...

Multifrequency electron paramagnetic resonance spectroscopy on oriented single crystals of magnetically dilute Gd(III) ions in Gd0.004Y0.996(trensal) is used to determine the Hamiltonian parameters of ...
