Electronic control of structural asymmetry using varactor diodes is proposed for tunable nonreciprocal phase shift in composite right-/left-handed (CRLH) transmission lines constructed on a perpendicu...
This paper introduces an inverse design framework of metasurface based on the automatic differentiable rigorous diffraction interface theory. As a technical demonstrator, an optimized dual-layer free-...
A modified version of the Gradient Model is presented. With the formulation of the electric field inside a rough conductor, real roughness profiles can numerically be analyzed without mathematical iss...
A plasma based adaptive waveguide high-power microwave (HPM) protector is presented in this paper. The proposed structure is comprised of double layer structure with metallic slots perburated and sepa...
The emergence of space exploration and hypersonic platforms necessitates the development of sophisticated electronics, communication systems, and sensors that can endure prolonged periods of stable fu...
This paper presents a theoretical and experimental study of the effects of a twist on the hybrid HE11V and HE11H mode propagations of X-shaped plastic waveguides. Plastic waveguides, providing a light...
Heart rate serves as an important indicator for evaluating health and fitness. This paper addresses the constraints of skin-contact sensors by introducing an innovative non-contact heart rate monitori...
A novel cost-effective displacement measurement technique based on low-IF Doppler radar is introduced in this paper. This technique only requires the acquisition of a single-channel IF signal, avoidin...
We demonstrate the joint detection of the radial and angular velocities of tagged moving objects using a harmonic radar with dual interferometric-Doppler measurement modes. The radar transmits a conti...
A novel radar interferometry technique is proposed to assess the dynamic rolling motion process for the self-rolled-up inductor made of SiNx nanomembrane. The rolling nanomembrane has an extremely sma...
