ANTENNAS
Understanding Phase Noise from Vibrating Antennas

Vibrating antennas distort signals. Previous analyses have focused on how physical distortion of the antenna structure changes beam patterns. The vibrational velocity and acceleration also have an effect, however, producing Doppler distortions that contribute heavily to noise at vibration frequencies up to 1000 Hz.


CALL FOR PAPERS Substrate Integrated Waveguides for MHz through THz

Submit papers by 1 October 2017 for the April 2018 IEEE Transactions on Microwave Theory and Techniques special issue on “Substrate Integrated Waveguide Circuits and Systems for MHz-Through-THz Wireless and Photonics Applications.”

MATERIALS Surface Roughness and Signal Loss

Experiments bear out simulations using new Gradient Model for the impact of surface roughness on signal loss and phase delay in typical transmission lines in the 100 GHz range.

YOUNG PROFESSIONALS Decoding the Professional Paper Submission Process

For younger engineers, members of the International Microwave Symposium’s Technical Paper Review Committee demystify the conference-paper submission and review process.

5G FOCUS Measurement Challenges for 5G and Beyond

A team of 23 NIST engineers outlines progress in their mission to identify and develop new measurement science for the next generations of wireless communications.

MEETING Radio Frequency Integration (RFIT2017, Seoul, 30 Aug-1 Sep)

Conference topics include device technologies, modeling, CAD, packaging, passive circuits and antennas, power ICS, mmWave and THz ICs, high-speed data transceivers, and much more.

THZ SPECTROSCOPY Identifying Transgenic Maize

Applying principal component analysis and a support vector machine method allows researchers to reliably identify genetically modified maize samples by their terahertz spectra, providing a fast alternative to gene or protein analysis.

OIL & GAS Novel, Inexpensive Water Fraction Sensing

A modified T-resonator, produced by screen printing and applied directly to the outside of oil-rig piping, accurately senses the water content of the flow within, without conditioning or homogenization.

WIRELESS POWER A New Way to Separate Tag-to-Reader Frequencies

A proposed approach for inductive wireless power transfer tag-to-reader communication employs a new method to separate transmitter and receiver frequencies.

COMING UP Wireless Power, Microwave Bio, Modeling and Optimization

Upcoming MTT-S-sponsored meetings include the International Microwave and Optoelectronics (IMOC2017, Brazil, 27-30 August), Radio Frequency Integration (RFIT2017, Seoul, 30 August-1 September), and Ubiquitous Wireless Broadband (ICUWB2017, Salamanca, 12-15 September).
