We propose a novel drug delivery system (DDS) by using a PANDA ring resonator to form, transmit and receive the microscopic volume by controlling some suitable ring parameters. The optical vortices (gradient optical field/well) can be generated and used to form the trapping tool in the same way as the optical tweezers. The microscopic volume (drug) can be trapped and moved (transported) dynamically within the wavelength router or network. In principle, the trapping force is formed by the combination between the gradient field and scattering photons, which has been reviewed. The advantage of the proposed system is that a transmitter and receiver can be formed within the same system, which is called transceiver, in which the use of such a system for microscopic volume (drug volume) trapping and transportation (delivery) can be realized.

This article discusses the tri‐core photonic crystal microstructure fiber for the process of simultaneous sensing for salinity and temperature of water substances. This kind of microstructure is preferred in many sensing application to scale the detection process in micrometer range. In this novel sensor, the sensitivity is calculated through coupling mechanism by tracking wavelength shift of various concentrations of salinity and temperature using finite element method. The sensible samples are in liquid and are infiltrated into the framed hollow cavity. Based on the coupling principle between silica substrate and the analyte material, the sense of the salt as well as temperature is obtained. Finally, it is noted that sensitivity of the salt level in water as 5404.9 nm/RIU for x polarization direction and 5674 nm/RIU for y polarization direction have been calculated with the temperature sensitivity of 4 nm/°C in the same water substances.

We propose the interesting results of light pulse propagation within a double PANDA ring resonator system. We use the technique of finite difference time domain that is implemented by the scientific programming method known as OPTI-WAVE PROGRAMMING to simulate and analyze the dynamic wave forms of propagating light pulse within the desired system. By using the input Gaussian pulse with center wavelength at 1550 nm and the other practical parameters into the system, results obtained have shown that the multiwavelength light sources can be generated and achieved, and the dynamic behaviors of light pulses propagating within the system can be seen.

Dual wideband operation of a notched CPW-fed pentagonal monopole antenna with experimental and numerical results has been presented. By means of embedding notches to the ground and the pentagonal radiating patch, enhancement of impedance bandwidth for the antenna can be achieved, while also reduces the required antenna size. The antenna is simple for fabrication and easy integration with the system circuit that it is a good candidate for applications in wireless communication systems.
