Directive Ultra-Wideband Planar Antennas

, 2010
The logical thread of this chapter can be summarized as follows. Highly directive, planar UWB antennas are gaining more and more attention, as required in many novel and important applications. As the modern antenna design deals with low profile structures, new ways of increasing the directivity of a candidate radiator can be explored.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.
