==Explanation==
Let B be the original diffracting body, and B' its complement, i.e., the body that is transparent where B is opaque, and opaque where B is transparent. The sum of the radiation patterns caused by B and B' must be the same as the radiation pattern of the undisturbed beam. In places where the undisturbed beam would not have reached, this means that the radiation patterns caused by B and B' must be opposite in phase, but equal in amplitude.
 
Diffraction patterns from apertures or bodies of known size and shape are compared with the pattern from the object to be measured. For instance, the size of [[red blood cell]]s can be found by comparing their diffraction pattern with an array of small holes. One consequence of Babinet's principle is a [[physical paradox|paradox]] that in the [[diffraction limit]], the radiation removed from the beam due to a particle is equal to twice the particle's [[cross section (physics)|cross section]] times the flux. This is because the amount of radiation [[absorption (electromagnetic radiation)|absorbed]] or [[Reflection (physics)|reflected]] is the same as the amount [[diffracted]].
 
The principle is most often used in [[optics]] but it is also true for other forms of [[electromagnetic radiation]] and is, in fact, a general theorem of diffraction and holds true for all waves. Babinet's principle finds most use in its ability to detect ''equivalence'' in size and shape.
 
==Demonstration experiment==
The effect can be simply observed by using a [[laser]]. First place a thin (approx 0.1&nbsp;mm) wire into the laser beam and observe the diffraction pattern. Then observe the diffraction pattern when the laser is shone through a narrow slit. The slit can be made either by using a [[laser printer]] or [[photocopier]] to print onto clear plastic film or by using a pin to draw a line on a piece of glass that has been smoked over a candle flame.
 
==Babinet's Principle in Radiofrequency Structures==
Babinet's Principle can be used to find complementary impedances. Babinet's Principle states (in optics) that when a field behind a screen with an opening is added to the field of a complementary structure (that is a shape covering the screen hole), then the sum is equal to the field where there is no screen. Demonstration can be found in any good optic or antenna book (such as Balanis, Krauss, Stuzman). The end result (corollary as a matter of fact) of practical interest for antenna engineers is the following formula:  
 
:<math>Z_{metal} \, Z_{slot}  = \eta^2 /4,</math>
 
where Z<sub>metal</sub> and Z<sub>slot</sub> are input impedances of the metal and slot radiating pieces, and <math>\eta</math> is the intrinsic impedance of the media in which the structure is immersed. In addition, Z<sub>slot</sub> is not only the impedance of the slot, but can be viewed as the complementary structure impedance (a dipole or loop in many cases). In addition, Z<sub>metal</sub> is often referred to as Z<sub>screen</sub> were the screen comes from the optical definition. It is noteworthy that the thin sheet or screen does not have to be metal, but rather any material that supports a <math>\vec{J}</math> (current density vector) leading to a magnetic potential <math>\vec{A}</math>. One issue with this equation, is that the screen must be relatively thin to the given wavelength (or range thereof). If it is not, modes can begin to form or fringing fields may no longer be negligible.
 
For a more general definition of Eta or intrinsic impedance, <math> \eta = \sqrt{\frac{\mu}{\epsilon}} </math>.
Note that Babinet's principle does not account for polarization. In 1946, H.G. Booker published ''Slot Aerials and Their Relation to Complementary Wire Aerials'' to extend Babinet's principle to account for polarization (otherwise known as Booker's Extension). This information is drawn from, as stated above, Balanis's third edition ''Antenna Theory'' textbook.

Bees need protection and because of colony collapse disorders, their number are reducing. The sudden change in levels of histamine results in a dimished power to resist allergens, thus causing hives. Avoid alcohol and coffee or other caffeine con¬taining beverages. They often appear for unknown reasons, on any part of the skin and can last for just hours or perhaps even days. - Circular Patches on the body - Raised welts on the skin - Red and itchy circular patches, occurring in batches - All size of patches, ranging from millimeters to centimeters - Usually occurs on throat, legs, arms and trunk.

Whether you live rural area or in a city, beekeeping is accessuble to all. Any liver disease such as hepatitis B or C or alcohol abuse should also be consulted with doctor. Nut products, dairy, wheat, citrus, strawberries, and eggs are often the culprit. The recommended time for harvesting is on a sunny day or when the bees are foraging for food. The space available on your block of land and the placement of the hive also need to be looked at.

Eminent by its dark red, itchy, and raised skin bumps, urticaria is induced mostly due to allergies. This will help in healing hives and will reduce itching. Many of us use these primarily in conjunction with home remedies or until their Hives Treatments can take control of the hives symtpoms. The allergy bears a striking resemblance to a mosquito bite and keeps on changing in shape, size and even locations. Homeopathy has been used as a leading remedy for hives for numerous years now and has been verified quite valuable in treating this problem.

Persistent urticaria will also be associated with a leukocytoclastic (white blood cell-mediated) vasculitis confined to skin and to a wider area involving connective tissue. Otherwise, spending too much time focusing on bugs with a mission could leave your overall troop lacking in support. This could be caused by an allergic reaction or from some unknown cause. It is a condition that is characterized by the development of various types of extremely itchy and swollen pink or red bumps or patches on the skin. The home remedies for hives will not only treat the welts, but it will also relieve the itching.

If one partner is a restless sleeper, quilted toppers minimize movement and distribute weight evenly to provide both parties with a restful sleep. You can either destroy Raynor’s Command Center or Infest it with a Queen. Ordinary hives can be widespread dissemination of and even intimidating, but most random hives usually do not lead to life-threatening additional complications. You can also count those hives you eliminated during your missions towards your total goal. I then only included the people in my study that had broken out in hives when I gave them the "Abracadabra" treatment.

Destroying them first makes assaulting the main base much easier. These could bring some relief from itching and redness and help the body to re-balance itself. Mix half cup of corn starch, and half cup of baking soda. Researchers have discovered that it is possible to have one, or two of the gene which causes Asian flush. Children will love learning about the homes, habits and diet of these favorite insects.
