5G-What’s the Latest Information on how it will Affect our Health?
The coming of 5G has had many people worried about "how will all of that RF radiation affect my health?" since its rollout in 2018. The concern about cell phones in general and their radiation emission has increased over the years, as people spend more time on them and near them than ever before. The FCC developed the Specific Absorption Rate (SAR) in 1996, at a time when the cell phone was just a phone. The SAR reflected the average...

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 to...

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 are...

Humans and Machines both Need Testing before they Can Work Together in Groups!
Just as the Medical Profession currently struggles with the testing difficulties of determining the presence of a COVID-19 infection or antibodies to determine the presence of this serious condition before people can resume their normal social lives, Electronic Engineers must struggle to locate and eliminate RFI (Radio Frequency Interference) and EMI (ElectroMagnetic Interference) which can impede their new components from working smoothly with other system components before they can safely bring them together as a team. EMI, has been defined as...

E-Smog, a New Presence by a “True Original” Participant in the RF/EMI Shielded Clothing Market!
E-Smog, one of the original brands in RF/EMI Shielded Clothing, is returning to the market with some new styles. You are able to test the Shielding Effectiveness (SE) of the garments using RF meters and various other methods of testing. Though there are many different testing methods available, one fact remains constant. No matter what method of testing is used, there is a surprising difference in the level of RF/EMI exposure between no coverage (bare skin), coverage with regular clothing,...

Radio Frequency Devices: Are They Harmless, or are We Playing With Fire?
Microwaves have long been known to cause damage to body tissues when used at amplified power levels. The noticeable damage caused at those exposure levels is basically heat-related, causing toasted skin syndrome, with "possible" links to tumors due to fragmented DNA, mutated cells, and cancers. It has also been speculated that even lower power microwaves can possibly impact the central nervous system, causing symptoms of dizziness, confusion, and memory issues. The American neuroscientist, Allan Frey, who first noted in 1961 what...

Fly Me to the Moon….with the Least Amount of Interference Possible!
NASA has announced that its next moonshot will be a joint public-private project called Next Space Technologies for Exploration Project (NextSTEP). Eleven United States companies are being asked for help in designing the spacecraft systems that will facilitate the successful completion of this project. This project will culminate with the first woman and next man to walk on the moon arriving there in 2024. A portion of their work will be funded by NASA, and the companies will be expected...
