Design of delay elements in a binary optical true-time-delay device that uses a White cell.

چکیده
A White-cell-based binary optical true-time-delay device has two parts: the controller, or switching engine, and the delay elements. Here we discuss in detail the design of both glass blocks and lens trains as delay elements. Glass blocks can be used in our design for delays ranging from one to a few hundred picoseconds. Lens trains are suitable for longer delays. We also analyze the loss associated with each design and give design limits.

Design and demonstration of a switching engine for a binary true-time-delay device that uses a white cell.
Optical true-time-delay devices based on the White cell can be divided into two general types: polynomial cells, in which the number of delays that can be obtained is related to the number of times m that a beam bounces in the cell raised to some power, and exponential cells, in which the number of delays is proportional to some number raised to the power of m. In exponential cells, the topic t...
متن کاملDelay-Scheduled Controllers for Inter-Area Oscillations Considering Time Delays
Unlike the existing views that was introduced the existence of delay caused by the transmission of wide area measurement system data (WAMS) into the controllers input of the power oscilation damping (POD) by communication networks as a reason for poor performance of the POD controllers. This paper shows that the presence of time delay in the feedback loop may improve the performance of a POD co...
