A review on planar printed structures that are based on Matryoshka-like geometries is
presented. These structures use the well-known principle of Matryoshka dolls that are …

In this work, we present a multiband FSS with open matryoshka elements obtained by the
insertion of a gap in the matryoshka ring. Taking into account the unit cell dimensions, very …

In this paper the resonant behavior of frequency selective surfaces, FSS, using matryoshka
geometry is analyzed considering polarizations x and y. The basics of the FSS using …

In this paper, a compact matryoshka DGS using dielectric resonator (DR) is proposed.
Despite the use of dielectric resonators to obtain band-stop frequency response not being a …

This paper introduces the use of calcium cobaltite ceramic of composition Ca3Co4O9, C349,
for miniaturization of a defected-ground-structure (DGS) filter based on matryoshka …

With the continuous evolution of telecommunications systems, the use of wireless sensor
networks also grows, which demands the development of sensors that can be integrated into …

A sensor using a Defected Ground Structure (DGS) based on the matryoshka geometry is
described. The main idea is to take advantage of the miniaturization and selectivity …

Os filtros desempenham um papel fundamental nos sistemas de telecomunicações. Embora
seja uma das tecnologias mais consolidadas na Engenharia de micro-ondas, o intenso …

A reconfigurable frequency selective surface, FSS, associating cross dipoles and
matryoshka geometries is described in this paper. The proposed reconfigurable FSS uses …

Os filtros são utilizados em sistemas de comunicação com a função de selecionar
frequências, atenuando-as ou não. Pesquisas recentes, com foco na miniaturização, baixo …
