In this letter, the maximal achievable bandwidth of an Archimedean spiral antenna above a reflector is investigated. This bandwidth is defined by the frequency range where the gain in the broadside ...

Abstract: A pair of equally excited but oppositely sensed Archimedean two-wire spirals situated close to one another in the same plane-a doublet-is used to generate a linearly polarized field in which ...

Structural transformation is a unique characteristic of atomic clusters, but it turns out very different from cluster to cluster. This theoretical study proves that the isomeric transformation between ...

Crafted with 18K Desert Gold, the phone showcases an Archimedean spiral pattern, a golden apple emblem, a reinforced gold frame, and side buttons, blending symmetry, elegance, and durability.

Publishes review papers aimed at mathematical physicists, mathematicians, theoretical physicists. Original research papers have expository part for wider readership than experts.

Hayes told Klein that Musk’s purchase of X had turned out to be “an enormous, almost Archimedean, lever on the electorate.” If that was true, the lever may have cranked back against him.

Limiting the dynamics of paramagnetic tags is crucial for the accuracy of the structural information derived from paramagnetic nuclear magnetic resonance (NMR) experiments. A hydrophilic rigid 2,2′,2″ ...
