What are Faraday Cages and How are they Used?
Faraday Cages are enclosures first researched by Benjamin Franklin in 1755, but mostly attributed to the work done by Michael Faraday in 1836. Essentially, a Faraday Shield is an enclosure made of a continuous covering of walls, ceilings, and floors by a conductive metal that is used to completely block Electromagnetic Fields from entering the inside of the enclosure by spreading the current over the outside of the enclosure. In contrast, a Faraday Cage, which involves the use of a...

Forensic Evidence (Faraday) Bags-Keeping Electronic Evidence Secure inside a Faraday Cage
We are all aware of the proliferation of electronic devices that we use in our daily lives, in fact, most of us have several electronic devices that we use regularly. These devices can be our cell phones, which have essentially become miniature computers that keep track of our appointments, finances, email, phone calls, and text messages. Additionally, we have our computers, tablets, and PDA's. All of these devices help us to keep our lives in order by making our information...

Compliance Test Tension? An RF Shielded Enclosure by V Technical Textiles, Inc. can Ease the Stress!
We all know that final EMI Compliance Testing can be a tense time. Time has been invested in development, design, prototyping, and now it is time to find out if your device is compliant with applicable ElectroMagnetic Compliance (EMC) standards. You drive the three hour trip to the testing site on your appointed day. Of course, the line has formed and "they're running a little behind today", so you wait for your turn. You hand your device over to the...

RF Protective Suit, Protection for 5G Workers, Microwave Workers and Maintenance Personnel!
Most of us know that we are surrounded by RF radiation all of the time. This radiation is of the non-ionizing variety, meaning that it lacks the energy to damage the DNA of a cell and cause mutations. RF is routinely absorbed by the body and the effects of this absorption are called "thermal effects", basically much as a microwave oven can heat water, RF radiation can rapidly warm the body. The eyes and the testes are most vulnerable to...

Want to Keep your Servers Free from Unwanted Intrusion? Put them in an RF Shielded Rack Enclosure!
A business stores a lot of valuable and sensitive information on its servers, hopefully, they also have firewalls and antivirus/antimalware software in place to prevent hacking the system through the internet connection. An offsite encrypted backup also helps to take away some of the risk of a ransomware attack. Improving digital security is part of the never ending chess game between today's digital criminal and computer security developers. One new way of accessing a company's most sensitive information is by...

RF Shielded Faraday Bags and Pouches, use Military Grade Technology to Protect Sensitive Digital Information Stored on your Electronic Devices!!
For years, the Military, the Police, and the Government agencies have been aware of the need to secure sensitive information and communication equipment such as phones and computers, that can be accessed by WiFi or other wireless means. Whether it was done by use of a specialized room called a Sensitive Compartmented Information Facility (SCIF, pronounced "skiff"), or by placing the devices in Faraday Bags and Pouches. In the legal system, it is commonplace for computers, phones, and other electronic...

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...

Digital Criminal Evidence-There is Proper Security Protocol for Keeping Digital Evidence Admissible in Court, Let Us Help You Handle Your Evidence Securely!
Despite the amazing amount of great evidentiary material that Forensic Sciences can provide, the care and treatment of evidence seized while in Law Enforcement custody can affect whether this persuasive information gathered through investigation will ever be presented in court or will be tossed out as "inadmissible in court". We all remember the O. J. Simpson trial, where "gold standard DNA evidence" was not allowed to be used as evidence in the trial due to a break in the "chain...
