Ferromagnetic inductors on commercial nanoporous anodic alumina

2009 European Microwave Conference (EuMC), 2009
This paper studies the feasibility of integrated devices on nanoporous anodic alumina substrates filled with ferromagnetic nanowires. The presence of ferromagnetic material is responsible for an increase of the permeability at low frequency, and a tunability in frequency when an external DC magnetic field is applied.

Controlling the surface functionalities of nanoporous alumina membranes [PDF]

, 2010
A new approach for controlling and to functionalise nanoporous anodic alumina oxide (AAO) membranes is described. Our approach is predicated on the remarkable stability of the silanised AAO surface during anodisation.

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.
