Resumo:

The anisotropic hexagonal magnetic material is prepared using conventional ceramic process. The high magnetic anisotropy field of hexagonal is essential to extend the device bandwidth for circulator operating at millimeter wave band. The modified hexagonal BaFe12-xCoxO19 with about 9 kOe anisotropy field and its Electromagnetic property are presented. And a simulation certificating the circulator at Ka-band is given at the end of the paper.

Resumo:

Barium ferrite films were prepared using screen printing method for their applications in self-biased microwave integrated circulators. The influences of alignment magnetic field on the microstructure and magnetic properties of the barium ferrite thick films were investigated. The results show that the (00l) peaks of the barium ferrite films are enhanced with the increase of alignment magnetic field. Hexagonal BaFe 12 O 19 platelets rotate and orient with c-axis perpendicular to the film plane after the magnetic field aligning. The remanence ratio of the barium ferrite films is improved from 0.52 to 0.78 with the increase of alignment magnetic field from 0 to 8 kOe. By magnetic field aligning, barium ferrite thick films with the remanence ratio of 0.8 have been prepared. A prototype of microwave integrated circulator is developed with the prepared barium ferrite films.

Resumo:

L’objectif de cette thèse est de développer une technologie de composants à ferrites ultra-compacts pour les futurs systèmes de communication spatiaux à très haut débit. Plus précisément, la thèse consiste au développement de circulateurs et d’isolateurs sans aimants (autopolarisés) en bande W spatiale (71 – 76 GHz / 81 – 86 GHz), diminuant ainsi leur taille et leur masse. Ce travail se concentre sur deux technologies : guide d’ondes et microruban. Les travaux en technologie guide d’ondes ont permis d’aboutir à la création de deux circulateurs utilisant des matériaux magnétiques différents présentant de très bonnes performances. Pour aboutir à la création d’isolateurs, la problématique de la conception de charges adaptées a été explorée via l’utilisation des techniques d’impression 3D. Grâce à la création d’un matériau ferrite dont les propriétés magnétiques sont contrôlées, un autre type d’isolateur ultra-compact a ainsi pu être réalisé, permettant leur utilisation dans les antennes actives. Enfin, la réalisation d’isolateurs autopolarisés microrubans en bande W a été rendue possible grâce à la compréhension de l’impact des effets de bords sur les performances électriques. Cela a abouti au développement d’une nouvelle technique de design relâchant les contraintes technologiques pesant sur ces composants, notamment celles liées à l’épaisseur du substrat. Ainsi, deux isolateurs planaires ont été fabriqués et mesurés. Ils offrent des performances à l’état de l’art. Une étude en température confirme la stabilité des performances RF et la robustesse de la conception vis-à-vis de l’environnement spatial
The goal of this thesis is to develop a technology of ultra-compact ferrite-based devices for futures very high throughput space communication systems. More specifically, this Ph.D. thesis consists of the development of magnetless (self-biased) circulators and isolators in space W-band (71 – 76 GHz / 81 – 86 GHz), lowering their sizes and weights. This work is focused on two technologies: waveguide and microstrip. Work in waveguide technology leads to the creation of two circulators using two different magnetic materials showing very good performances. In order to create isolators, matched waveguide terminations has been designed and manufactured using 3D printing techniques. With the help of a custom-made ferrite material with controlled magnetic properties, another type of ultra-compact isolator has been manufactured, allowing their use in active antennas. Finally, the realization of self-biased microstrip isolators in W-band is now possible thanks to the deep understanding of the impact of fringing fields on electrical performance. This led to the development of a new design technique that relieve technological constraints, especially ones that are linked to the substrate thickness. Hence, two planar isolators have been manufactured and measured. They offer state-of-the-art performance. A temperature analysis confirms RF performance stability and the design reliability in the context of the space environment

Resumo:

Contemporary U.S. political discourse is distorted by “epistemic bubbles.” In social epistemology, an epistemic bubble is a self-segregated network for the circulation of ideas, resistant to correcting false beliefs. Dominant models of epistemic bubbles explain some of their features, but fail to account for their recent spread, increasing extremity, and asymmetrical distribution across political groups. The rise of populist authoritarian politics explains these recent changes. I propose two models of how populism creates epistemic bubbles or their functional equivalents: (1) by promulgating biased group norms of information processing; and (2) by replacing empirically-oriented policy discourse with an identity-expressive discourse of group status competition. Each model recommends different strategies for popping epistemic bubbles. My analysis suggests that social epistemology needs to get more social, by modeling cognitive biases as operating collectively and outside people’s heads, via group epistemic and discursive norms.
