OSRR-based BPF with Square Groundplane Window

Estimation of Common Groundplane Based on Co-motion Statistics

The paper presents a method for groundplane estimation from imagepairs even if unstructured environment and motion. In a typical outdoor multicamera system the observed objects might be very different due to noise coming from lighting conditions and camera positions. Static features such as color, shape, and contours cannot be used for image matching in these cases. In the paper a method is pro...

Compact Balanced UWB BPF Based on HMSIW and D-DGS

A compact balanced UWB bandpass filter (BPF) is proposed in this paper, which is based on the half-mode substrate integrated waveguide (HMSIW) and the differential defected ground structure (D-DGS). Using the HMSIW, the filter can achieve compact size, wide passband and good compatibility. Two D-DGS cells are employed to provide good suppression for the common-mode (CM) noise, while they have s...

Window Annealing over Square Lattice Markov Random Field

Monte Carlo methods and their subsequent simulated annealing are able to minimize general energy functions. However, the slow convergence of simulated annealing compared with more recent deterministic algorithms such as graph cuts and belief propagation hinders its popularity over the large dimensional Markov Random Field (MRF). In this paper, we propose a new efficient sampling-based optimizat...

Randomization Can't Stop BPF JIT Spray

Multi-strip LTCC resonator BPF

Multi-strip resonator BPF is fabricated in the LTCC configuration. The center frequency is 3.5GHz, fractional bandwidth is 0.1 and 3-stage Chebyshev type is designed. The relative permittivity of the ceramic is 18.3, resulting in the size as small as 2.3 × 1.6 × 0.73mm. The in-band loss is 3.5 dB, which could be reduced in the stable mass production state. The spurious suppression of more than ...
