Deterministic Constrained Synthesis Technique for Conformal Aperiodic Linear Antenna Arrays - Part I: Theory
IEEE Transactions on Antennas and Propagation. 2019. Vol. 67. No. 9. P. 5951–5961.
A deterministic approach to the synthesis of a
general aperiodic arc or ring antenna array is presented and
thoroughly detailed in this paper. The proposed technique, which
is based on the auxiliary array pattern (AAP) concept, is aimed at
the semianalytical determination of the optimal excitation tapering
and array element angular distribution for mimicking a given
radiation pattern mask, without resorting to any optimization
procedure. This, in turn, enables a dramatic reduction in design
times. The developed technique is validated by application to the
synthesis of antenna arrays featuring different radiation pattern
masks typically adopted in satellite communications and radar
applications; the relevant results are reported in Part II.

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

In this study, we analyze the dielectric function of high-Tc cuprates as a function of doping level, taking into account the full energy band dispersion within the CuO2 monolayer. In addition to the conventional two-dimensional (2D) gapless plasmon mode, our findings reveal the existence of three anomalous branches within the plasmon spectrum. Two of these branches ...

The development of new algorithms for simulations in physics is as important as the development of new analytical methods. In this paper we present a comparison of the recently developed microcanonical population annealing (MCPA) algorithm with the rather mature Wang-Landau algorithm. The comparison is performed on two cases of the Potts model exhibiting a first ...

Nabokoite family compounds ACu7(TeO4)(SO4)5Cl (A=Na, K, Cs, Rb) are one of the candidates for the evasive spin-liquid state predicted for highly-frustrated square kagome lattice (SKL). Their magnetic subsystem includes SKL layers decorated by additional copper ions. All members of this family are characterized by quite high Curie-Weiss temperatures (∼80−200 K), but magnetic ordering was reported ...

A detailed investigation of a superconducting spin-triplet valve is presented. This spin-valve consists of a superconducting film covering a metal with an intrinsic spiral magnetic order, which could result from competing isotropic exchanges or, if the crystal lattice breaks central symmetry, from asymmetric Dzyaloshinskii-Moriya exchange. Depending on the anisotropy, such a metal may change its ...
