What will you be doing?
In a lot of applications you can find optical research of TNO, for example: in monitoring the size of the hole in the ozone layer, optimizing oil production, mobile phone chips and in non-invasive glucose measurements for diabetics. The Optics Research Group (70FTE) is one of the leading Optics groups within Europe for design and development of high-performance optical solutions.
TNO Optics works closely together with other research groups within the Nanotechnology Cluster in Delft (200FTE), in particular, with Opto-Mechatronics, Space Systems Engineering and Nano-Instrumentation for the development of new instruments for Space and Semiconductor Equipment applications. Combining our knowledge of optics with expertise available in these research groups enables us to offer complete measurement solutions to our customers. This is strengthened by extensive in-house laboratory facilities and specialized manufacturing capabilities.
What do we require of you?
We are now looking for an intern for:
Development of a lens for wide scanning phased arrays (Master >6 months):
Active/Phased arrays on board of airborne platforms are required to have low profile and mass for aerodynamic and mechanical integration. At the same time, they are required to steer electronically the beam over a very large angular range to guarantee the satellite communication when flying also at high latitudes. A properly designed lens structure on top of the antenna array would allow to satisfy all these challenging requirements.
As an intern you will be working on an analysis with Grasp and comparison with ray-tracing results. You will be developing code for optimization of 2D dielectric lens (based on the existing 3D dielectric lens analysis tool and the 2D phase surface optimization tool). You will (together with your supervisor) be responsible for the assessment of non-imaging optics design techniques to shape the lens. Next to that you will be performing a theoretical study of the impedance matching due to coupling variation in case of not linear phase distribution on the array elements and you will work in the design of matching layers for the lens to reduce reflections and possible surface waves.
As an intern we require you to be a Master student in Physics or Electrical Engineering with a specific interest and an expertise in Optics/Electromagnetics. If you recognize yourself in this profile and are enthusiastic about the assignment, feel free to apply for the position of intern at the Optics department.
What can you expect of your work situation?
TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society.
