Nesting isn’t just for Birds, Nested Enclosures Help to Determine Shielding Effectiveness!
The determination of the Shielding Effectiveness (SE) of a material at high frequencies/small wavelengths can give large variations in results based on the testing method employed. One of the methods used to get more consistent results is to use a "nested" testing chamber, meaning a testing chamber is divided by a shielded wall across the middle of the chamber, with a window/hole in it. On the receiving side, there is no mode stirring and the antenna is set up...

Good News!! Copper Kills Bacteria and Viruses on Contact!
Copper, which has been used and valued in the world's civilizations for centuries, now appears to have a new value in both antimicrobial and antiviral function. The antimicrobial function of metallic copper is described in papers by as the "metallic copper killing bacteria on contact", meaning that the population of bacteria a on a bare metal copper surface is continually decreasing at a rate of seven to ten logs per hour. M. Vincent, R.E. Duval, P. Hartemann, and M....

A Tale of Two Metals, Bad News for the “Bugs”!
Silver and Copper, over the centuries, these two metals have been used as currency, jewelry, electronic conductors, and in many other ways. Silver and Copper also share a valuable medical functionality, and before the advent of antibiotics in the 1930s, both were major assets used in wound care and disinfection. It's not surprising that these two metals function in similar fashion, they are vertical neighbors on the Periodic Table of the Elements, which means that they react in the...

COVID-19 is NOT Finished with Us yet, Please Keep Your Masks and Your Distance!!
Many people are worried that the "second wave" of COVID-19 has arrived with summer. I tend to agree with Dr. Anthony Fauci, who has stated "we are still in the first wave of COVID-19". People just got tired of making the effort that is necessary to keep the rate of the infection down to manageable levels for our medical system and assumed that "this crisis is over". I believe that COVID-19 is going to take our country to...

Space Force Moves into a New Era, Partnering with Private Companies for Defense
The Space Force is smaller than the other military forces and will be very much more "technology dependent" in order to accomplish its mission of protecting the military on the ground by monitoring events occurring on earth from space. Much of the Space Force's mission will be accomplished with the use of satellites. The Space Force is planning to follow the lead of NASA, by partnering with private businesses that are already involved in the aerospace field like SpaceX...

Robots are Good Workers, but can Make a lot of Noise in the Testing Room. An Absorber Sleeve can Quiet things Down!
Antenna manufacturers make antennas for many uses. The end user of each antenna needs to know the characteristics of the antennas to make sure that they are performing to their specifications. The "characteristics" of an antenna's transmission and reception of signals are called the antenna's patterns. These pattern measurements must be VERY precise and done with the antenna in many different positions during testing. In order to make sure that the position of the antenna is correct, robotic arms...

Back to School, New Rules for an Old Routine will be in Play this Year!
We live in interesting times, COVID-19 has turned our routines, our economy, and our lives upside down for the last two and a half months. We are talking about "Re-Opening America" and "Getting things back to Normal" more and more each day. One of the biggest concerns about reopening the economy is "how can the parents go back to work if the kids can't go back to school safely?" The elephant in the room that no one is talking...

Have you ever seen or felt the sticky material that is present in the base of your pet's water bowl? It looks bad to the eye and feels bad to the touch, slick and gooey all at the same time. The material is called a "biofilm", which means a sticky film that is home to millions of bacteria. These bacteria, when swallowed by your pet, causing a variety of microbial infections in the pet: urinary tract infections, middle ear... 27Feb
