Notes Uploaded on July 15, 2011
Carl Baum has been editing and publishing these "Notes" for over four decades. This was one of his many good deeds to our technical community. We continue this tradition with one difference: There will be no hard-copy distribution of the Notes. The manuscripts that are received are reviewed, revised and uploaded to http://www.ece.unm.edu/summa/notes. This notice announces that 14 new publications have been uploaded.
In SSN553, Giri has reported on modifying a commercial IRA for use in monostatic impulse radar. Kumar and Baum investigate radiation of THz frequencies from switched oscillators in SSN554. Farr describes antenna parameters in the time domain useful for pulsed antennas in SSN555. In SSN556, Vega et al., describe various impedance transformers to drive a 100 Ohm half-IRA from a 50 Ohm source.
CESDN69 and IN614 were the last couple of Notes authored by Carl Baum prior to his untimely demise. His writings are extensive in quality, quantity and variety. Larry West has stimulating ideas on various aspects of Lightning interaction to electronic equipment as described in IN615, IN616, IN617 and IN618. Nitsch et al., look at the pulsed excitations of resonators in IN619. In IN620, Kohlberg has a new way of looking at critical infrastructure components and how they may recover following a malicious event.
Tesche and Giri look at the "old" problem of complex natural frequencies of a wire antenna/scatterer in IN621, prompted by a recent paper in IEEE Transactions on AP-S that uses a variational principle approach. Finally Farr et al., describe an automated way of RF effects testing in MN63.
On behalf of the editorial board of the Note Series, I wish to thank the authors and reviewers of these publications for their contributions in maintaining the high-standards of the Note Series set by Carl Baum. I am also grateful to Chuck Reuben for his assistance.
