Metamaterials perform ‘photonic calculus’
The discovery that metamaterials can be designed to perform ‘photonic calculus’ as lightwaves pass through them could give rebirth to analog computers. Computational metamaterials could almost instantly perform operations on the original wave, such as the light coming in through the lens of a camera, without conversion to electronic signals.
