Dual-band transmittance defogging model
Applied OpticsThe fusion of shortwave infrared (SWIR) and visible light has emerged in recent years as an effective technique for image defogging. However, in some dense fog scenes, even this fusion method does not achieve significant defogging effects. Some researchers have attempted to apply atmospheric scattering models for defogging fusion images; overlooked is ...

Integrating a dual‐band filter into the dual‐band VCO module to achieve harmonic suppression
Microwave and Optical Technology Letters, 2008AbstractA dual‐band voltage‐controlled oscillator (VCO) module is proposed by integrating a novel dual‐band filter with a dual‐band VCO. The resonator designed with the LC‐tuned concept in the VCO is capable of switching between two frequency bands.

Design of a Dual Band Gan Pa Utilizing Dual Band Impedance Transformers
This thesis discusses the design, fabrication, and testing of a high efficiency, dual band radio frequency power amplifier. While it is difficult to demonstrate an exact mode of operation for power amplifiers at radio frequencies, based on the characteristics of the transistor itself, the argument can be made that our high efficiency performance is dueopenaire +1 more source

Dual-band ends-fed dipole-like driver for dual-band antenna arrays
RadioengineeringThe article addresses the problem of dual-band structure designs based on the quasi-Yagi arrangements. The reported dual-band dipole antenna comprises the out-of-phase power divider, whose outputs excite the corresponding dipole arms to produce appropriate surface current distribution on them.
