The Toucher-Isolator game

Know Thy Toucher

Most of current academic and commercial surface computing systems are capable of multitouch detection and hence allow simultaneous input from multiple users. Although there are so far only few applications in this area which rely on identifying the user, we believe that the association of touches to users will become an essential feature of surface computing as applications mature, new applicat...

Broadband Faraday isolator.

Driving on an analogy with the technique of composite pulses in quantum physics, we theoretically propose a broadband Faraday rotator and thus a broadband optical isolator, which is composed of sequences of ordinary Faraday rotators and achromatic quarter-wave plates rotated at the predetermined angles.

A Broadband Waveguide Thermal Isolator

This paper describes a new, compact, waveguide thermal isolator. The isolator is based on a recently developed microwave bandgap joint, a periodic structure which suppresses microwave fields propagating between two parallel conducting surfaces. When such a structure is placed between a pair of waveguide flanges, the flanges can be separated by a few percent of a wavelength before the leakage an...

Integrated magnetooptic cross strip isolator

A bimodal planar waveguide segment of specific length and thickness between two thinner single mode sections can serve as an interferometer. Depending on the phase gain of the two modes in the thick region, these fields can interfere destructively or constructively at the transition from the bimodal to the single mode section. We employ this geometry to realize a simple magnetooptic isolator co...
