There is an increasing interest in utilizing underwater electromagnetic signals for communication purposes in marine environment. Difficulties encountered in implementing high bandwidth underwater data communication system arise from high propagation loss. This loss can be reduced considerably by using partial air path between submerged transmitters and receivers. With a view to analyzing propagation...
This paper discusses a tunable optical filter designed using the two-dimensional (2D) photonics crystal square lattice (PCSL). The filter has been designed to work in Dense Wavelength Division Multiplexing (DWDM) communication using rectangle resonant cavity. The filter analysis was initially carried out by changing the attributes of photonic crystal such as the radius of inner ring pillars and refractive...

Physical Unclonable Function (PUF) provides, efficient and cheap authentication. PUF is a device that harnesses the entropy of a physical system. A PUF will generate a specific bit pattern response for a specific challenge. But different instances of the same PUF circuit will produce different bit patterns. Since the response depends on the inherent properties, the attacker cannot replicate the PUF...
