Branch Cross-Correlation in Presence of Spatially Selective Interference Expressed in Terms of the Spherical Vector Wave Expansion of the Electromagnetic Field
نویسندگان
چکیده
In this paper we present an analysis of the cross-correlation coefficient between signals at two antenna branches (ports) in the presence of spatially selective interference and additive white gaussian noise. More specifically, we look at a ±45◦ slanted polarization diversity arrangement, which is rotated around the axis perpendicular to the plane containing the antennas. Results are provided as a function of the rotation angle. The analysis is based on the spherical vector wave multi-pole expansion of both the field impinging on the antennas and the antenna radiation properties.

On the Mean Effective Gain Expressed in Terms of the Spherical Vector Wave Expansion of the Electromagnetic Field
The mode expansion offers a general framework for the analysis of the interaction between antennas and propagation channels. In this paper, the Mean Effective Gain (MEG) of an antenna is expressed in terms of the spherical vector wave expansion of the electromagnetic field. An explicit expression of the MEG is provided as a function of the normalized average power of modes excited in the propag...

Casimir entropy is an important aspect of casimir effect and at the nanoscale is visible. In this paper, we employ the path integral method to obtain a general relation for casimir entropy and internal energy of arbitrary shaped objects in the presence of two, three and four dimension scalar fields and the electromagnetic field. For this purpose, using Lagrangian and based on a perturb...

متن کاملA New Theorem Concerning Scattering of Electromagnetic Waves in Multilayered Metamaterial Spherical Structures
The proposed theorem in this paper is indicative of a kind of duality in the propagation of waves in the dual media of and in the spherical structures. Independent of wave frequency, the number of layers, their thickness, and the type of polarization, this theorem holds true in case of any change in any of these conditions. Theorem: Consider a plane wave incident on a multilayered spheric...
