Menger Fractal Acoustic Metamaterials with Double-Negative Property

2019 Thirteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials), 2019
We construct new three-dimensional fractal acoustic metamaterials by adopting Menger structure, which have the double-negative property with a single structure. By adopting the finite element method and S-parameter retrieval method, the effective parameters of the acoustic metamaterials with different fractal orders are researched separately.

Weaker forms of the Menger property in bitopological spaces

Quaestiones Mathematicae, 2018
In this paper we continue previous investigations on the weaker forms of the Menger property in bitopological spaces. We introduce weakly Menger property and study some topological properties of almost and weakly Menger bitopological spaces. We also consider the almost Hurewicz spaces in a bitopological context.

On weaker forms of Menger, Rothberger and Hurewicz properties

2009
Summary: We introduce new star selection principles defined by neighbourhoods and stars which are weaker versions of the Menger, Rothberger and Hurewicz properties; in particular the properties introduced are between strong star versions and star versions of the corresponding properties defined in [\textit{L. D. Kočinac}, Publ. Math. 55, No.~3--4, 421--

Consonant spaces of countable type and the Menger property

Topology and its Applications
If a topological space \(X\) is consonant and either of weak closed countable type or regular and of countable type then \(X\) has property P which in turn is equivalent to the Menger property at infinity provided that \(X\) is completely regular. The product of countably many spaces having property P also has property P.
