In this letter, we define amicable complex orthogonal designs (ACOD) and propose two systematic methods to construct higher-order ACOD’s from lower-order ACOD’s. Although the upper bound on the number of variables of ACOD’s is found to be the same as that of amicable orthogonal designs (AOD), we show that certain types of AOD’s that were previously shown to be non-existent or undecided, such as...

Abstract— This work investigates the improvement of the active reflection coefficient of waveguide-fed phased-array antenna using liquid crystal layers. The anisotropy properties of liquid crystal layer can be employed to eliminate blind scan angle and improve the wide angle impedance matching of the waveguide-fed phased array antennas. The authors have expressed the modal analysis of the waveg...

In this survey we review the recently developed theory of anisotropic spaces and representations of functions based on anisotropic multilevel ellipsoid covers (dilations) of Rn. We also exhibit the relations of the ellipsoid cover approach to earlier concepts of anisotropic structures as well as to the framework of general spaces of homogeneous type. A number of open problems are presented and ...

This paper proposes range-based distributed single-hop and scalable 3D node localization algorithm by using the application of Biogeography Based Optimization in anisotropic Wireless Sensor Networks (WSNs). In anisotropic networks, radiation patterns are not uniform. An anisotropic property of propagation media and heterogeneous properties (different battery backup statuses) of the devices are ...

The generalization of the hard thermal loop effective theory to anisotropic plasmas is described with a detailed discussion of anisotropic dispersion laws and plasma instabilities. The numerical results obtained in real-time lattice simulations of the hard loop effective theory are reviewed, both for the stationary anisotropic case and for a quark-gluon plasma undergoing boost-invariant expansion.

We present an anisotropic diffusion model for volumetric image filtering. Our 3D anisotropic diffusion tensor is constructed to enhance 1D features (curves) and 2D features(surfaces). Bilateral prefiltering is employed to construct more accurate anisotropic diffusion tensor. An efficient parallel implementation has been done on a PC cluster, the performance and speed-up are reported also.
