A system for investigating a plurality of samples having varying positions or orientations moving with respect to the system, the system including an emitter of terahertz radiation for irradiating a sample provided in a sample space; a detector of terahertz radiation configured to detect radiation reflected from said sample space; and determining means to determine if radiation reflected from said sample space is from a sample with a predetermined orientation in the sample space.

Terahertz investigative system and method

An antenna comprising a photoconductive material () and a plurality of spaced apart electrodes () provided on said photoconductive material (), each electrode () having at least one facing edge which faces a facing edge of an adjacent electrode, a physical barrier () being provided abutting a facing edge of at least one electrode (), said barrier () extending to at least the full height of said facing edge.

Electrodes on a photoconductive substrate for generation and detection of terahertz radiation

An emitter for emitting radiation in a first range of frequencies comprising: a photoconductive material (); and first and second contact elements () separated by a photoconducting gap provided by said photoconducting material (), for applying a bias across said photoconducting gap, wherein at least one of said first and second contact elements () comprises a resistive element () for restricting current flow between said first and second contact elements in a second range of frequencies lower than the first range of frequencies.

Coherent THz emitter with DC power reducing resistor

A semiconductor material with photoconductive properties and a method of the semiconductor, wherein a base material is grown and then annealed post-growth at a temperature of 475&#xb0; C. or less. It has been found that be annealing at temperatures of 475&#xb0; C., or less the carrier lifetime of the material and the resistivity can be optimized so as to obtain semiconductor with useful photoconductive properties.
