An optical panda ring resonator connecting to two microring resonators (MRRs) can be used to generate a high frequency optical soliton. The optical soliton pulse of 57-61 GHz can be generated and transmitted via an optical quantum transmission link. This system uses a Gaussian laser pulse propagating within a nonlinear MRRs system. The ultra-short single and multi soliton pulses within the range of 57-61 GHz can be generated and seen at the through and drop ports of the system. The transmission link consists of MRRs system, optical transmitter, connector, fiber optics, erbium doped fiber amplifier (EDFA), receiver and antenna which provide transmission of optical soliton via the wired/wireless communications. The fiber optic has a length of 1 km, where the wireless link covers a short distance optical communication of 10 m. Here, the transmitted optical soliton pulses can be received, detected and used by the users.

An arc shape ultra-wideband (UWB) antenna design with different configurations is the part of the discussion during this paper by implementing a ground-penetrating radar (GPR) technology specifically for search and rescue applications. The simulated antenna used a defected ground structure method for the bandwidth enhancement i.e. 3-16 GHz, possess gain around 6.2 dB. The complete detection model for multiple configurations i.e. monostatic and bistatic was simulated. The radar cross-section (RCS) for defined models is studied and compared in order to detect the obstacle. The analysis shows that a bistatic configuration for antenna developed a clear image for detection behind the obstacle.
