in the following detailed description , reference is made to the accompanying drawings , which form a part hereof , and in which is shown by way of illustration specific embodiments in which the inventions may be practiced . these embodiments are described in sufficient detail to enable those skilled in the art to practice the invention , and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the spirit and scope of the present invention . the following detailed description is , therefore , not to be taken in a limiting sense , and the scope of the present invention is defined only by the claims and equivalents thereof . embodiments of the present invention provide an electromagnetic radiation system that eliminates or minimizes blood splash , achieves stunning in a very short time ( less than one second ), with capital costs and operating costs being much more in line with the cost of electrical stunning . in embodiments , electromagnetic radiation ( in the radio frequency ( rf ) or microwave spectrum ) is split into two paths with a power splitter . the paths direct the electromagnetic radiation to come together forming constructive interference ( electric and magnetic waves in same phase ) at a focal point within the animal &# 39 ; s brain . the animal &# 39 ; s brain is heated at the focal point by the constructive interference of the electromagnetic radiation stunning the animal . the process is further beneficial because the heating area of the brain is localized so that the surrounding tissue is not harmed therein providing less waist of the product . referring to fig1 , an illustration of an electromagnetic stunning system 100 of one embodiment is illustrated . as illustrated , the system 100 includes a radiation generator 102 . the radiation generator in one embodiment generates electromagnetic radiation in the rf frequency range and in another embodiment generates electromagnetic radiation in the microwave range . the generated electromagnetic radiation 200 is directed to a power splitter 104 . the power splitter 104 splits electromagnetic radiation into two paths . in particular , a first portion 200 a of the electromagnetic radiation is split into a first waveguide 106 a and a second portion 200 b of the electromagnetic radiation is split into a second waveguide 106 b . the first portion 200 a and the second portion 200 b will be “ in phase .” the respective first and second waveguides 106 a and 106 b direct their respective first and second electromagnetic radiation portions 202 a and 202 b to paths that converge . since the first portion 200 a and the second portion 200 b of the electromagnetic radiation are in phase , constructive interference will occur at their convergence point ( focal point 108 ). hence , at the focal point 108 , the magnitude of the first and second portions of the electromagnetic radiation 200 a and 200 b is the sum of the individual magnitudes of the first and second portions of electromagnetic radiation 200 a and 200 b . the animal to be stunned is positioned so the focal point 108 is within the animal &# 39 ; s brain at a select location . at the focal point 108 , the animal &# 39 ; s brain will heat up therein stunning the animal . the desired temperature increase for stunning would be approximately 10 - 15 ° f . hence , a pigs temperature prior to stunning is about 101 - 103 ° f ., an increase of 15 ° f . would raise the temperature to 116 - 118 ° f . at the select location to accomplish stunning . fig2 provides an illustration of an animal head 250 that is positioned between the waveguides 106 a and 106 b . illustration includes ears 255 a and 255 b . as discussed above the waveguides 106 a and 106 b direct their respective first and second portions of the electromagnetic radiation 202 a and 202 b to converge at a focal point 260 . at this focal point 260 , constructive interference of the radiation 202 a and 202 b signals takes place heating up the tissue . in one embodiment , the waveguides 106 and 106 direct their respective first and second portions of electromagnetic radiation 202 and 202 to the focal point 260 which is located at the brain stem of the animal . fig3 illustrates the total power to the brain as a function of axial position around ear represented xy graph 300 . this graph 300 illustrates that by adjusting the axial location of the animal head relative to waveguides 106 a and 106 b , the total power to the brain can be maximized . fig4 illustrates a power to the hypothalamus part of the brain as a function of axial position around ear xy graph 400 . the graph 400 illustrates the optimum location of the head relative to waveguides 106 a and 106 b to maximize power absorbed by the hypothalamus . referring to fig5 a stunning station 500 of one embodiment is illustrated . as illustrated , the stunning station includes a holding compartment 502 in which an animal would be restrained . the stunning station 500 includes a positioning portion 504 that is designed to position the animal head in a location in relation to the waveguides 106 a and 106 b . the positioning portion in one embodiment , also acts as a shield to localize the electromagnetic radiation . as discussed above , the waveguides 106 a and 106 b deliver electromagnetic radiation that creates constructive interference at a focal point that is within the positioning portion 504 . the waveguides 106 a and 106 b would be coupled to receive electromagnetic radiation 200 a and 200 b from a power slitter 104 that splits electromagnetic radiation 200 from an electromagnetic generator 102 . although specific embodiments have been illustrated and described herein , it will be appreciated by those of ordinary skill in the art that any arrangement , which is calculated to achieve the same purpose , may be substituted for the specific embodiment shown . this application is intended to cover any adaptations or variations of the present invention . therefore , it is manifestly intended that this invention be limited only by the claims and the equivalents thereof .
a method of stunning an animal for slaughter is provided . the method includes directing a first portion of electromagnetic radiation in a first side of the animals head and directing a second portion of the electromagnetic radiation in a second side of the animals head such that the first portion and second portion of the electromagnetic radiation achieve constructive interfere at a focal point within the animal &# 39 ; s head .
