Correlation and Capacity Calculations with Reference Antennas in an Isotropic Environment

open access: yesInternational Journal of Antennas and Propagation, 2012
A reverberation chamber is a convenient tool for over-the-air testing of MIMO devices in isotropic environments. Isotropy is typically achieved in the chamber through the use of a mode stirrer and a turntable on which the device under test (DUT) rides ...

Cross-isotropic strength criteria based on spatial plane variation

open access: yesYantu gongcheng xuebao, 2022
The geotechnical materials in nature are affected by the natural sedimentation and often have significant cross-isotropic characteristics. The difference in strength and deformation of structural units of soil in different directions is the main issue ...

Circles of Curvature at Points of Parabola in Isotropic Plane [PDF]

open access: yesMathematica Pannonica, 2021
The authors have studied the curvature of the focal conic in the isotropic plane and the form of the circle of curvature at its points has been obtained. Hereby, we discuss several properties of such circles of curvature at the points of a parabola in the isotropic plane.

Modeling and numerical simulation of elasto-viscoplastic anisotropic behavior of tantalum including the ductile damage effect [PDF]

open access: yesComputer Methods in Materials Science, 2009
At room temperature, the tantalum is shown to exhibit a high and typical strain rate sensitivity.Various experimental tests including uniaxial tensile tests for the three in-plane directions,relaxation and cyclic shear tests have been conducted at room ...

Dyakonov-Tamm wave at the planar interface of a chiral sculptured thin film and an isotropic dielectric material [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2007
Surface waves, named here as Dyakonov-Tamm waves, can exist at the planar interface of an isotropic dielectric material and a chiral sculptured thin film (STF).

Propagation of inhomogeneous plane waves in isotropic solid crystals

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper we study the impact of initial mechanical deformation and electric fields applied to linear elastic isotropic solid, on the propagation of inhomogeneous plane waves in such media. We derive the decomposition of the propagation condition for

Weighted minimal translation surfaces in the Galilean space with density

open access: yesOpen Mathematics, 2017
Translation surfaces in the Galilean 3-space G3 have two types according to the isotropic and non-isotropic plane curves. In this paper, we study a translation surface in G3 with a log-linear density and classify such a surface with vanishing weighted ...

On the Feuerbach Point and Feuerbach Line in the Isotropic Plane

open access: yesMathematica Pannonica, 2023
In this paper, we consider the Feuerbach point and the Feuerbach line of a triangle in the isotropic plane, and investigate some properties of these concepts and their relationships with other elements of a triangle in the isotropic plane. We also compare these relationships in Euclidean and isotropic cases.
