Abstract: A method and a system are provided for collecting volatile organic compounds and applying THz based detection of a signature of the collected compounds to determine egg properties. Egg properties include gender and/or fertility.

Abstract: Optical switch and modulator devices are described, usable for Terahertz data communication rates. The device comprising an optically transmissive substrate configured for propagating electromagnetic radiation therethrough and a metamaterial arrangement optically coupled to said substrate. The metamaterial arrangement comprises at least one layer of metamaterial particles optically coupled to at least some portion of said optically transmissive substrate, and at least one nanomesh layer made of at least one electrically conducting material placed over at least some portion of the at least one metamaterial layer.

Abstract: A high throughput method for label-free, noncontact, noninvasive, and nondestructive detection of at least one virus infected or virus free individual from at least one tested individual is provided. The method includes collecting a sample from exhaled breath of a subject for analysis of the sample. The collecting includes the subject exhaling into at least one sampler and collecting aerosols and/or any airborne compound from the exhaled breath by passing the exhaled breath through a metamaterial membrane within the sampler. The metamaterial membrane is arranged transverse to a flow of exhaled breath through the sampler. The method further includes analyzing the sample for detection of at least one virus infected individual from at least one tested individual.

Abstract: A device for producing an electromagnetic radiation of predetermined properties is configured as a layered structure and includes a light interacting layer, in communication with at least one light emitting source, and having one or more light interacting regions, each configured to define a closed-loop light mixing path for optically coupling a pair of input coherent light components of predetermined first and second frequencies to create an output radiation component of a third beating frequency of a predetermined high-frequency profile. The device further includes a control layer interfacing with said light interacting layer and configured for controllable switching between inoperative opaque and operative transparent states with respect to the at least one third beating frequency, to selectively prevent and allow transmission of the at least one output radiation component of the third frequency towards a medium in the vicinity of the layered structure.
