The mainstream types of chipless tags are digitally encoded and work at more than one millimetre range, like silicon chips. Their potential markets go beyond the lowest cost-highest volume potential markets because they have other attributes beyond cost.
or red shift. noun, Astronomy. 1. a shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth. Compare cosmological redshift, Doppler effect, gravitational redshift. Origin of redshift.
However, this was sufficient to indicate that the redshift was probably not a smooth function at all. If these results were accepted, then the whole interpretation of the redshift, namely that it represented the expansion of the cosmos by a Doppler effect on light waves, was called into question.
