The Division provides support to projects, preparatory programmes and technology programmes. Within this frame, the Structures Section is in charge of all structural engineering aspects. Interested candidates are encouraged to visit the ESA website related to the Divisions activities. Fields of activitiesresearch The proposed activity will involve integrating thermal, materials, mechanical, structural and optical domains into a multidisciplinary process with the aim of enabling a deterministic assessment of, for example, optical performance. The successful candidate will be assigned to the Structures Section and will work on the conception, analysis and development of analysis methodologies and software tools for optomechanical analysis and will work closely with mechanical, thermal, materials and optical engineers. In this context, the Research Fellow will be asked to participate in one or more of the following activities Structural modelling and analysis of optical components, optomechanical assemblies and optical payloads to assess structural integrity, dimensional stability and material selection for architecture downselect Thermoelastic structural analysis to evaluate the pointing control and stability, wave front error, coregistration and alignment of optical components and payloads Development of analysis software tools with a focus on optomechanical analysis Evaluation or benchmarking of relevant commercial software tools Support materials test programmes for the evaluation of the mechanical and thermal properties of optical materials, coatings and adhesives Support mechanical and optical test programmes, including the development and application of tools for mathematical model correlation between analytically predicted and experimentally validated optical alignment, coregistration and wavefront error. Technical competencies Ability to conduct research autonomously Breadth of exposure coming from past andor current researchactivities Researchpublication record Knowledge relevant to the field of research Interest in space and space research Ability to gather and share relevant information Behavioural competencies Innovation Creativity Continuous Learning Self Motivation Communication Problem Solving Relationship Management CrossCultural Sensitivity Education Applicants should have recently completed, or be close to completion of a PhD in mechanical engineering, with some background in the topics to be addressed e.g. structural analysis, materials, optics, mechanical and optical testing, software development. Preference will be given to applications submitted by candidates within five years of receiving their PhD. Additional requirements The candidate should have ideally participated in the design or development of ground or spacebased optical payloads or instrumentation. Some experience in the mechanical design, assembly, alignment and testing of optical instrumentation would be an asset. The Research Fellow must be able to work in a team with other international investigators in a spirit of positive cooperation and, at the same time, be capable of working autonomously in hisher area of research. At the end of the fellowship, the Research Fellow will be required to summarize the work completed in papers to be submitted to specialized conferencesjournals. The working languages of the Agency are English and French. A good knowledge of one of these is required. Knowledge of another Member State language would be an asset. Other information For behavioural competencies expected from ESA staff in general, please refer to the ESA Competency Framework. The Agency may require applicants to undergo selection tests. The closing date for applications is 19 October 2017. In addition to your CV and your motivation letter, please add your proposal of no more than 5 pages outlining your proposed research. Candidates must also arrange for three letters of reference to be sent by email, before the deadline, to temp.htresa.int. The letters must be sent by the referees themselves. The candidates name must be mentioned in the subject of the email. If you require support with your application due to a disability, please email contact.human.resourcesesa.int.

NIST Optomechanical Transducer links sound, light, radio waves.
2016-03-30 14:31:08| Industrial Newsroom - All News for Today
Published in Nature Photonics, researchers at NIST developed "piezo-optomechanical circuit" that converts signals among optical, acoustic, and radio waves. According to one of said paper's co-authors, Kartik Srinivasan, this device might enable detailed studies of interactions and foster development of phononic circuitry that can be modified with photons. "This work," said Srinivasan, "presents one platform for transducing information between different carriers."
