On the basis of a delicate balance between gain and loss, these synthetic structures exhibit rich and unconventional behaviour, holding promise for numerous applications in nano photonics and lasers 36. In particular, structures with a so-called parity time (PT) symmetry 29, 30, were recently introduced theoretically 31, 32, 33 and experimentally 34, 35 in the context of paraxial waveguide optics. Largely in parallel to these efforts on disordered media, it was recently realised that materials and devices can get entirely new functionalities when adding to them a suitably arranged combination of gain and loss. More recent studies focused instead on controlling the medium itself, for example, through the material fabrication process 22 or through a spatially modulated pumping 23, leading, for example, to a versatile control of random and micro-cavity lasers 24, 25, 26, 27, 28. In a first generation of corresponding experiments the focus was laid on shaping the input wave front impinging on an immutable disordered sample such as to achieve a desired output, like a spatial or temporal focus behind the medium 18, 19, 20, 21.

Remarkable progress in these endeavours has recently been made in the optical domain, largely due to the availability of spatial light modulators and new concepts for how to apply them on turbid media 16, 17. While much work has been invested into understanding the ‘statistical’ properties of the corresponding wave phenomena 13 there has recently been a surge of interest in controlling the scattering of waves through ‘individual’ systems for specific purposes such as detection, imaging, and efficient transmission across disordered materials 14, 15.

Among the many important physical aspects of wave propagation that have been studied the phenomenon of Anderson localisation has received particular attention 4, 5, 6, 7, 8, 9, 10, 11, 12. Upon simplification, the intensity (I) is found to be approximately 1.33 × 10 -3 W/m 2.The scattering of waves through disordered media is a paradigmatic phenomenon that has captured the interest of various communities for quite some time now 1, 2, 3. We can calculate the intensity (I) using the formula: Let’s assume we have an electromagnetic wave with an electric field strength (E) of 50 V/m. Therefore, you only need one of these values to calculate the intensity of an electromagnetic wave. It is important to note that the electric and magnetic field strengths are related by the equation B = E/c. B is the magnetic field strength in tesla (T).E is the electric field strength in volts per meter (V/m).c is the speed of light in a vacuum, approximately equal to 3 × 10 8 m/s.

ε 0 is the permittivity of free space, approximately equal to 8.85 × 10 -12 C 2/N.

μ 0 is the permeability of free space, approximately equal to 4π × 10 -7 N/A 2.

I is the intensity of the electromagnetic wave in watts per square meter (W/m 2).

The formula for intensity (I) is given by: To calculate the intensity of an electromagnetic wave, we need to consider two primary factors: the electric field strength (E) and the magnetic field strength (B). Calculating Electromagnetic Wave Intensity The unit of intensity is watts per square meter (W/m 2). In the context of electromagnetic waves, intensity refers to the energy carried by the wave as it propagates through space. Intensity is defined as the amount of energy transmitted per unit area, per unit time. In this article, we will discuss the formula used to calculate the intensity of electromagnetic waves and break down the key components involved in the process. Understanding the intensity of these waves is crucial to grasping their behavior and potential applications. Calculating the Intensity of Electromagnetic WavesĮlectromagnetic waves are a fundamental aspect of our daily lives, from the visible light we see to the radio waves used in communication.

To calculate the intensity of electromagnetic waves, use the formula I = 1/2 μ₀ c E² or I = 1/2 ε₀ c B², with E or B field strength given.
