This raises the possibility of identifying the carcinogens and/or tumour promotors concerned and by neutralising or eliminating them from the diet, reduce the cancer incidence.(More)
Reflectarrays composed of resonant microstrip gold patches on a dielectric substrate are demonstrated for operation at terahertz frequencies. Based on the relation between the patch size and the reflection phase, a progressive phase distribution is implemented on the patch array to create a reflector able to deflect an incident beam towards a predefined(More)
