Complex Permittivity of Dielectric Substrate Measurements Using Ring Resonator
Abstract: In this paper, we are going to present a methodology which is more suitable and easy to measure complex permittivity of dielectric substrates using ring resonator of a planar circuits. Mainly it is based on the transmission type ring resonator with capacity coupling. On adjusting base resonant frequency of a ring resonator we can measure the dielectric constant and dissipation factor at wide frequency band and the remaining parameters can …

Micro-Doppler Signatures for Human with Orbbec Sensor
Abstract: Micro-movements, such as oscillations, rotations or revolution of an object or structures persuade additional frequency modulations on reinstate radar signal, which generates sidebands about the object’s Doppler frequency, called micro-Doppler effect. Human body mechanics consist of various moving body parts, which generate unique micro-Doppler signatures. Using TFT (time frequency transforms and pattern recognition techniques; we can classify individuals based on their movements using micro-Doppler signatures. Preliminary results from a laboratory …
