Kernel ridge regression for generalized graph signal processing
Published 2023“…To perform non-linear filtering and regression under the GGSP framework, we formulate an operator-valued kernel ridge regression (KRR) filtering approach. Under a specific choice of separable kernels, we show that this problem is equivalent to learning a nonlinear frequency response on each frequency band. …”

Broadband and Low-Profile H-Plane Ridged Horn Antenna
Published 2016“…By employing stepped ridges and an ellipse-shaped copper taper extended along the horn aperture, the proposed antenna achieves a wide bandwidth from 4.2 GHz to 18 GHz for VSWR 2 while retaining the antenna height of only 5.508mm. …”

Single-mode narrow beam divergence surface-emitting concentric-circular-grating terahertz quantum cascade lasers
Published 2013“…In addition, the devices show a peak output power approximately three times higher than in conventional ridge-waveguide lasers of similar size, whilst maintaining similar threshold current densities and maximum operating temperatures.…”

Experimental investigation on fracture resistance behavior of additivemanufacturedmultimaterial structure with corrugated interface
Published 2016“…In this study, a PolyJet system is used to fabricate multi material structure which consists of matrix layers (Tango black plus) sandwiched by two reinforcement layers (Vero white).In this work, interface between reinforcement and matrix layer in flat and corrugated shape (sine-wave ridged pattern) is employed. Corrugated shape is commonly found in nature and engineering structure in order to produce a compliant bending was employed in AM multi material structure to enhance its flexural properties. …”
