• Module structure in Conley theory with some applications

  Publikacja

  • Z. Dzedzej

  - BANACH CENTER PUBLICATIONS - Rok 2014

  A multiplicative structure in the cohomological versjon of Conley index is described . In the case of equivariant flows we apply the normalization procedure known from equivariant degree theory and we propose a new continuation invariant. The theory is then applied to obtain a mountain pass type theorem. Another application is a result on multiple bifurcations for some elliptic PDE.

• Compact 4 × 4 butler matrix with non‐standard phase differences for IoT applications

  Publikacja

  • A. Bekasiewicz
  • S. Kozieł

  - ELECTRONICS LETTERS - Rok 2021

  Butler matrices represent a popular class of feeding networks for antenna arrays. Large dimensions and the lack of flexibility in terms of achievable output phase difference make conventional Butler structures of limited use for modern communication devices. In this work, a compact planar 4 × 4 matrix with non-standard relative phase shifts of –30º, 150º, –120º, and 60º has been proposed. The structure is designed to operate at...
