EMC shielding solutions for labs & chambers

Following the increase in the need in the modern world for research laboratories, sensitive computerized systems, information security for laboratories and research facilities
The importance of the electromagnetic environment (EMG) that is expected to prevail in research laboratories, sensitive microscopes, computer systems, information security, and research facilities is increasing.

The absolute and increasing dependence on computing and sensitive electronic means lead to disruptions in the functioning of the ELM, the development of software threats (cyber) and threats of severity (electromagnetic terrorism).

With the advancement of technology, people and equipment are increasingly surrounded by electromagnetic radiation of different frequencies and different intensities.
The buildings we live in and work in may sometimes be a significant source of different levels of electromagnetic radiation, both in the surroundings of the buildings and from them.

The electric field:

The electric field is a component of the electromagnetic field, the electric field is developed by electric charges or by changing magnetic fields.
The electric field is a vector with a magnitude and direction that can be described as E: the intensity of the electric field, knowing the value of E at a certain point without any information about the source of the development of the field is all the information necessary to know how an electric charge close to that point will behave.

The strength of the electric field E at each point is defined by the electric force F acting on a stationary test charge charged with a positive charge q at the point.

The magnetic field:

A magnetic field is another component of the electromagnetic field which develops around an electric current or a permanent magnet, the magnetic field is a vector and is defined at any point in space as having a magnitude and direction.
The magnetic field is divided into two groups – permanent and variable magnetic field.
A permanent magnetic field, or magnetostatic field, will develop in the vicinity of a permanent magnet, or a wire in which a constant electric current flows in one direction, in such a case the magnetic vector will be the same in size and direction everywhere in space.
A changing magnetic field will develop in an alternating current environment where in this case the magnetic field will change at any given moment in both its magnitude and direction.

The magnetic field is defined mathematically by two different vectors that represent the magnetic field: the magnetic flux density represented by the letter B and measured in Tesla units T or Gauss T=10,000G and the strength of the magnetic field represented by the letter H and measured in ampere units per meter A\m, where H and B proportional to each other and defined as:

where is the permeability coefficient (permeability) of the material or medium.
B is actually a vector with magnitude and direction, and as we have seen: a particle with a charge q will experience a force F in the presence of an electric field, in addition, it is known that if the same charged particle moves at a speed V perpendicular to B then it will experience a force F which is proportional to the magnetic flux density B, we can describe the force F by: , where X is a vector product, it follows that if the charge moves parallel to B the magnetic force in this orbit will be zero.
In the event that the same charge moves perpendicular to the magnetic field, then the magnitude of the force F will be the product of the product in the direction perpendicular to B and v, hence, according to Lorenz’s law:

And according to Bioswar’s law, the magnetic field B at point r relative to a charged particle q moving at speed v moving in space
