Compact, Multi-Band, Slot Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019This paper presents a novel multi-band slot antenna. The antenna’s different dimensions can be easily calculated for obtaining the desired resonance frequencies. The antenna presents a very good efficiency in the different resonant bands. Also, each resonance could be reconfigured independently from others.

Ultrathin Multi-band Terahertz Absorber
International Photonics and Optoelectronics Meetings, 2012We present a design of an ultrathin multi-band terahertz (THz) metamaterial absorber based on planar waveguide. With optimized parameters, eight absorption peaks with strengths greater than 90% distributing nearly entire THz range are obtained.

Multi-Band Digital-RF Receiver
IEEE Transactions on Applied Superconductivity, 2011A software radio receiver that can be programmed to operate in multiple wide frequency bands is required for many communication and intelligence applications. We have designed a variety of multi-band receivers, comprising a set of band-specific analog-to-digital converters (ADCs) for direct digitization of RF bands and a digital switch matrix for band ...

Multi-banded coherent WDM transmission
31st European Conference on Optical Communications (ECOC 2005), 2005The world's first 1.5 Tbit/s multi-banded coherent-WDM system is demonstrated, in which five co-polarised bands of 298 Gbit/s-NRZ channels are transmitted over 80.4 km of SMF-28e[reg ] in a simple cost-effective arrangement, with an aggregate spectral efficiency of 0.83 b/s/Hz.

Multi-band electronically scanned antennas
ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat. No.00EX364), 2002Foundations and principles of radio lenses constructed in millimeter wave ranges with controlled refraction index, combining the quality of phased array antennas with optical devices are stated. Possibilities of electronic scanning with wide-angle sector and high coefficient of amplification are maintained.

Multi-Band Infrared Camera Systems.
1994Abstract : The program resulted in one of the first IR camera systems to utilize a unique MOS addressable focal plane array with full TV resolution, electronic control capability, and windowing capability. Two systems were delivered, each with two different camera heads: a Stirling-cooled 3-5 um band head and a liquid nitrogen-cooled, filter-wheel ...
