Surface Acoustic Wave (SAW) devices, using interdigital electrodes, play a key role in today’s telecommunication systems and are widely used as electronic filters, resonators, delay lines, convolvers or wireless identification systems (ID tags). During the last three decades, demands set by the expansion of the telecommunication industry and many applications in sensor have resulted in the intr...

The extremely high data rates of optical computing technology (100 MWords per second and upwards) present unprecedented challenges in the dynamic memory design. An optical ber loop, used as a delay line, is the best candidate for primary, dynamic memory at this time. However, they pose special problems in the design of algorithms due to synchronization requirements between the loop data and the...

The peak power delivered by the klystrons in the NLCTA (Next Linear Collider Test Accelerator) now under construction at SLAC is enhanced by a factor of four in a SLED-II type of R.F. pulse compression system (pulse width compression ratio of six). To achieve the desired output pulse duration of 250 ns, a delay line constructed from a 36 m length of circular waveguide is used. Future colliders,...

We experimentally demonstrate complete compensation of pulse broadening in an amplifier-based slow light system. The configuration of the delay line basically consists of two stages: a conventional Brillouin slow light system and a nonlinear regeneration element. Signal pulses experienced both time delay and temporal broadening through the Brillouin delay line and then the delayed pulses were d...

We demonstrate a multilayer circuit board that has two orthogonal serpentine delay lines on different layers to read out event positions from a microchannel plate ~MCP!. The top serpentine is directly bombarded by the MCP. The orthogonal buried serpentine receives its charge through thousands of vias that connect to the top surface. Event X and Y positions are decoded with a timing circuit for ...

In this paper we proposed anovel multiband delay line which consists of two types of split-ring resonators: the broadiside coupled and the single split-ring resonator. Proposeddelay line exhibits two left-handed bands that can be shifted by twisting the split rings for certain angle or by changing their lengths. This delay line is suitable for design of multiband frequency scanning antennas sin...
