“…Simulation: by using the higher values of the complex component of electrical permittivity and tangent loss and the best frequency bands to which it can be applied for an electromagnetic radiation absorber material, the simulation was possible with Ansoft HFFS, by placing a block of the material, processed under the best conditions to obtain the highest values of the complex component of electrical permittivity, in a waveguide for observing the efficiency of absorption. Similar studies on the electrical properties of loss tangent and electrical permittivity of materials performed simulations for analyzing the propagation of electromagnetic waves in various environments and devices, including waveguides, but none of them proposed inserting a ceramic material with metallic particles for absorption of electromagnetic radiation [26][27][28][29][30]. According to information provided by EIA (Electronics Ind.…”

This work aimed to perform the characterization of electrical properties of niobium pentoxide, Nb 2 O 5 , pure and doped with molybdenum, prepared by powder metallurgy route and to do a comparative analysis of the influence of this material when sintered in a muffle or in a microwave oven. The results showed that the doping of the niobium pentoxide with 0.5% or 1% of molybdenum along with the process of sintering in a microwave oven make the material more applicable as a microwave absorber material for electromagnetic radiation in the UHF (ultra-high frequency) range between 0.3 to 3 GHz. The motivation of this work was associated with the fact that in Brazil are located two of the largest niobium reserves in the world. Under this view, the study of the processing of the ceramic materials is important considering possible technological applications.

“…In this article, we report all-dielectric NRMs that consist of selfbiased magnetic meta-atoms fabricated from La-doped BaFe 12 O 19 (La:BaM). Such M-type hexaferrites have a giant magnetic anisotropy of up to 17,500 Oe and a large magnetic coercivity [34][35][36][37][38] , and have been used to create radio-frequency isolators/circulators [37][38][39][40][41][42] . Their large coercivity and strong magnetic remanence supports magnetic bias-free operation of devices 34,43 .…”

A self-biased non-reciprocal magnetic metasurface for bidirectional phase modulation

et al. 2023

View full text Add to dashboard Cite

Non-reciprocal metasurfaces can encode optical functions on forward- and backward-propagating waves, and could be used to create non-reciprocal antennas and radomes for full-duplex wireless communication and radar systems. However, such metasurfaces typically require external electric- or magnetic-field biasing or rely on non-linear effects, which makes practical implementation challenging. Here we report a self-biased non-reciprocal metasurface based on magnetic meta-atoms made from lanthanum-doped barium hexaferrite. The metasurface offers a transmittance of up to 77% and an operation angle of ±64°. We show that they can be used for on-demand bidirectional phase modulation, which provides non-reciprocal functionalities including microwave isolation, non-reciprocal beam steering, non-reciprocal focusing and non-reciprocal holography. The approach could also be potentially extended to megahertz and optical frequencies by using different self-biased magnetic materials.

“…In combination with laser direct structuring (LDS), MID offer the possibility to design electrical and mechanical components on three-dimensional surfaces to increase functionality and integration levels and to reduce costs. For example, transmission lines, antennas, switches and connectors can be integrated on carriers such as the covers of mobile phones or the housings of car wing mirrors [27,28]. In contrast to classically manufactured electronic assemblies, MID technology enables the functionality of the entire component through freedom of design [24][25][26].…”

Towards a Tailored Engineering Design Process for Individualized Micro-Mechatronic Systems with a Novel Case-Based Methodology

2021

View full text Add to dashboard Cite

The development and manufacturing of high-precision micro-mechatronic systems (MMS) is a challenging task, and the high demand for individualized products complicates the engineering design process (EDP) in particular. The established EDP for MMS is not designed for individualized products. This article gives an overview of the challenges (critical factors) in product development and manufacturing of individualized MMS (iMMS), a novel definition of iMMS, and describes a new qualitative methodology in order to tailor an EDP based on use cases, so-called “Tailored EDP-Methodology” (TEDP-Methodology). This TEDP-Methodology allows creating use-case-based product groups through the abstraction of the use cases and evaluating the requirements, which is essential to tailor or develop a new EDP. For the development of this new approach, a literature review and qualitative content analysis are prefaced. The TEDP-Methodology is critically examined and validated with a real case study for the development and manufacturing of an iMMS. This study shows critical points within the EDP. It shows fields of action for innovative tools to support the development process of iMMS and requirements for different product groups within iMMS. This article has both theoretical and practical implications.
