TERAHERTZ BAND FOR EM BASED NANO-NETWORKS
J.M. Jornet and I.F. Akyildiz,
“Channel Capacity of Electromagnetic Nanonetworks in the
Terahertz Band”, in Proc. of IEEE ICC, Cape Town, South Africa, 2010.
– Developed an Attenuation and Noise model for EM
communications in the Terahertz Band (0.1-10 THz)
– Uniqueness of the Terahertz band:
* Terahertz channel is seriously affected by the
presence of different molecules present in the medium
* High molecular absorption attenuates the travelling
wave and introduces noise into the channel

PATH-LOSS
Determined by:
– Spreading Loss: accounts for the attenuation due to
the expansion of the wave as it propagates through
the medium.
– Absorption Loss: accounts for the attenuation due to
molecular absorption.

Medium-Range Communication using Catalytic Nanomotors
– Information is expressed as a set of DNA base pairs, the DNA packet, which is
inserted in a plasmid.
Encoding
Transmission Propagation
• Nanorods are introduced in a solution of
AEDP
• Magnetic Fields guide the
nanorod to the receiver
• AEDP binds with the Nickel segments
Decoding
DNA packet is
extracted from the
plasmid using:
 Restriction
• DNA packets (plasmids) are attached to
nanorods
endonucleases
enzymes
• CaCl2 solution is used in order to
compress and immobilize the plasmid
