Natã Franco Soares De Bem – A Novel Microcantilever with Integrated Force and Displacement Sensors

Date & Venue:
Friday, 18 October 2019
An atomic force microscope consists of three basic components: a microcantilever with a sharp probe at one end, an XYZ nanopositioner, and an optical beam deflection system to measure the tip deflection of the microcantilever due to interaction forces between the tip and sample. It is a versatile tool […]

Luke McCourt: Two Photon Near Field Lithography

Date & Venue
Tuesday, 26 March 2019, 3:00pm

The next generation of integrated circuits will be mass produced using extreme ultra violet lithography (EUV). The short wavelength light sources and optical masks required are prohibitively expensive with commercial systems costing upwards of $1M. Furthermore, the optical masks are unique to each IC design. Two photon near […]

Rudolf Seethaler: High Speed Motion Control Applications in the Automotive Industry

Date & VenueFriday, 08 March 2019, 02:00pmEF122

Abstract Motion control has been used in automation applications such as numerically controlled machine tools for many years.  With the advent of low cost microelectronics, motion control has spread into new products that often require extremely high performance position control.  Examples of this are hard […]

Arnfinn Eielsen: Dithering Techniques: New Results and Applications

Date & VenueMonday, 21 January 2019, 01:00pmEF122

Abstract   In non-linear systems where some form of averaging is present (inertia) or can be introduced (low-pass filter), it can sometimes be beneficial to purposefully introduce an additional noise or disturbance signal. This signal is known as dither, and the combination of a dither […]
