"The Plasma Antenna - Now you see it, now you don't"
Dr. Igor Alexeff, Professor Emeritus, University of Tennessee, Knoxville, D=
istinguished Lecturer, NPSS Society
Our plasma antenna is a fluorescent lamp from the local hardware store. Whe=
n on, it receives ordinary FM and AM signals. When off, it electrically dis=
appears and becomes invisible to RADAR. Our work on plasma antennas has bee=
n supported by two phase 2 SBIR grants from the US Air Force and the US Arm=
y. We have made many significant advances in theory and practice, the most =
important of which is that a plasma antenna under the proper operating cond=
itions has much lower thermal noise than metal antennas in the same operati=
ng frequency range. We have constructed an intelligent plasma antenna, whic=
h searches in azimuth for a desired signal. When a desired signal is found,=
the plasma antenna locks onto the desired signal, ignoring signals arrivin=
g at other azimuthal angles. When the desired signal disappears, the intell=
igent plasma antenna recommences scanning (movie).=20
Professor Alexeff graduated from Harvard in physics in 1952, and received h=
is PhD degree from the University of Wisconsin in nuclear physics in 1959. =
He also passed the Tennessee State License Exam, and is a registered profes=
sional engineer. He has worked at the Westinghouse Research Laboratory on n=
uclear submarines, at the Oak Ridge National Laboratory in controlled therm=
onuclear fusion, and at the University of Tennessee in industrial plasma en=
gineering. He has worked overseas for extended periods in Switzerland, Japa=
n, India, South Africa, and Brazil. He has done considerable work for the I=
nstitute of Electrical and Electronics Engineers, and was a co - founder of=
the IEEE Nuclear and Plasma Sciences Society. He was president of that soc=
iety in 1999 - 2000. He is a Fellow of the IEEE and of The American Physica=
l Society. He has over 100 refereed publications, 19 issued patents and pub=
lished a book.
He has spent considerable time recently on plasma stealth antennas, and is =
listed on several patents issued to the ASI Technology Corporation.
This meeting is sponsored by the IEEE Nuclear and Plasma Sciences Society D=
istinguished Lecturers Program and IEEE North Shore Subsection. Meeting ti=
me will be Wednesday, May 13th, 2009 at 6:30 PM at the University Massachus=
etts Lowell, Lowell, MA 01854, Ball 412. Refreshments will be served at 6:=
30 PM and the talk will begin at 7:00 PM. Following the lecture there will=
be a no host dinner held at a local restaurant.
Directions: To UMass Lowell North Campus from the Lowell Connector: From th=
e Connector, take Exit 5B onto Thorndike St. After four traffic lights (1/2=
mile), Thorndike St. bears right and becomes Dutton St. Continue on Dutton=
St. about 1/2 mile to Merrimack Street by City Hall. Proceed straight onto=
Arcand Drive. At the end of Arcand Drive, the Tsongas Arena is straight ah=
ead. Turn left at the traffic light onto Morissette Blvd. Wannalancit Mills=
is one block on the right. Proceed to the second light at Aiken Street. UM=
L East, Lelacheur Ball Park and the Campus Recreation Center are on the rig=
ht. On Morissette Blvd., continue to the third light and turn right onto th=
e University Ave Bridge. Once across the bridge, UMass Lowell North is on e=
ither side of the road.
All are welcome to attend the meeting and if you're planning to attend plea=
se call or contact: Prof. Dikshitulu Kalluri (978) 934-3318 or dikshitul..=
._at_uml.edu<about:blank> or Constantine Taki Markos (781) 883-0179 or c..._at_ie=

The other talk is partly about MoM, or Method of Moments, which is the tech=
nique used in NEC (EZNEC, etc.) for simulating antennas:
"MoM and FDTD electromagnetic modeling in MATLAB"
Sergey N. Makarov
This talk discusses results and challenges of antenna and electromagnetic m=
odeling in MATLAB including the 3D MoM solver and a 2D FDTD solver. The MoM=
solver requires two external LAPACK subroutines to be compiled in MATLAB. =
The problems to be considered:
1.. Small antennas (MoM)=20
2.. Antenna to antenna link (MoM)=20
3.. Patch antenna (MoM)=20
4.. Antenna array (MoM)=20
5.. Indoor propagation (FDTD)=20
In every case (except for #5), we compare the MATLAB MoM performance with t=
he performance of the commercial package Ansoft HFSS with regard to its exe=
cution speed and accuracy. The freeware MATLAB 64bit solvers discussed in t=
his talk have been written by graduate students of the Antenna Lab in the E=
CE Department at WPI.
Sergey N. Makarov (M'98-SM'06) earned his B.S./M.S./Ph.D./Dr. Sci. degrees =
at the St. Petersburg (Leningrad) State University, Russian Federation - De=
partment of Mathematics and Mechanics where he became a professor in 1996 -=
the youngest full professor of the Faculty. In 2000 he joined the Faculty =
in the Department of Electrical and Computer Engineering at Worcester Polyt=
echnic Institute, MA where he became a full professor and director of the C=
enter for Electromagnetic Modeling and Design at WPI in 2008. His current r=
esearch interests include practical antenna design, computational and analy=
tical electromagnetics, and educational aspects of electromagnetics and wir=
eless power transfer.
The meeting will be held at the MIT Lincoln Laboratory Cafeteria in Lexingt=
on, MA. Refreshments will be served at 5:30; the talk will begin at 6:00 p=
m. The talk is open to the general public.
Directions to Lincoln Laboratory Cafeteria from points north: Take I-95/128=
south to exit 31B, Routes 4 & 225 towards Bedford. Stay in right lane and =
use the right turning lane (0.3 miles) to access Hartwell Ave at first traf=
fic light. Follow Hartwell Ave to the end; take a left onto Wood Street (ju=
st before the AFB gate). Lincoln Laboratory entrance is 0.5 miles on right.=
The entrance to the cafeteria is on the lower level left of the main entra=
nce.
>From points south: Take I-95/128 north to exit 30B, Route 2A west. Turn ri=
ght on to Mass Ave (~0.4 miles). Turn left on to Wood Street (~0.4 miles) =
Lincoln Laboratory Wood Street entrance is 1 mile on left. The entrance to=
the cafeteria is on the lower level to the left of the main entrance.
