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...

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...

Size Problem? Large or Small, VTT can Help with your EMI Testing Needs!

Electronic devices come in many sizes, whether your device is the size of a cubesat, an automobile, military vehicle, or a spacecraft, V Technical Textiles can help you with your EMI Testing needs by providing you with one of our portable RF Shielded Testing Enclosures, specially designed for your testing needs. EMI testing follows two basic tests that determine if a device is fit to work in an environment with several types of electronic devices in it. The first test is...

“Hardening Structures”-Protecting our Country’s Vital Electronics-Based Systems!

ElectroMagnetic Pulses (EMPs), transient electromagnetic disturbances, evoke the Orwellian thoughts of nuclear explosions that are capable of short-circuiting a wide range of electronic equipment, including computers, satellites, radios, radar receivers, and even traffic lights, plunging the world into the "electronic dark ages".  Though a nuclear weapon is the most commonly thought of cause of an EMP, they can also be caused by solar flares, a close lightning strike, or a massive powerline short circuit.  The damage to electrical equipment can...

Portable RF Shielded Enclosures Provided Work from Home Applications During Covid-19

When Covid-19 hit North America in March, it closed down a lot of our businesses, but many businesses and individuals were able to continue to do work from home or other remote locations during the quarantine/social distancing period of this pandemic.  The "Work From Home" #wfh group, were often able to continue their work with the use of RF Shielded Enclosures and pouches. One didn't need to be in the electronics development business to benefit from these enclosures.  Government and Business...

The Constant Increase of Electronic Devices makes the Shielding Industry Very Important in Achieving EMC!

We have more electronic devices than ever before in this world, each of them adding to the invisible cloud of E-Smog that surrounds us all.  More of these devices are being developed all of the time, with the development in cellular infrastructure for the 5G and 6G communications systems....yes, I said 6G!!!  That doesn't include the aerospace and automotive industries as today's aircrafts and automobiles are essentially controlled and driven with the aid of complex electronic devices and the consumer...
Testing Situations-Prepare for them!

We Live in “Testing Times”, Make Your Testing Times Accommodate Your Schedule!

Students returning to school this Fall aren't the only ones who will have to prepare for rigorous testing to see if they meet the educational standards required of them to advance to the next level!  Companies that have been shut down during the pandemic are coming back to life, and hopefully, producing lots of new and different electronic devices that will be coming into the marketplace in various areas such as the aerospace, automotive, electronic, medical, along with military and...
Minimizing RF Radiation Exposure!-RF Shielded Garments!

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...

CubeSats, the Smallest Members of the Satellite Family

NASA has announced a Cube Satellite Launch Initiative (CSLI) recently, making it possible for a private company to propose a Cube Satellite (CubeSat) mission that will be deployed in space by a NASA booster that has space available on it for more cargo than it is scheduled to take into space.  In very simple terms, a CSLI means that NASA will "cover the cost" of putting your CubeSat mission into orbit in exchange for a report on the results of...

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...
