Investigation of frequency radiations of the human body

Siti Zura A. Jalil; Mohd Nasir Taib

This study discusses an investigation of frequency relationship of the human body radiation based on twenty-three points of radiation in the human body. The endogenous electromagnetic field of the human body is studied experimentally from 33 healthy human subjects. Different parts of the body radiation frequency are investigated separately into four groups of top, torso, arm and bottom. Statistical properties of body radiation frequency have been investigated. It is found that human bodies have different relationship of body radiation between males and females, where the most significant different was obtained on arm and top group.

This paper describes an analysis of body radiation frequency for the purpose of gender classification. The human radiation frequency is experimentally studied from 33 healthy human subjects of 17 males and 16 females. KNN classifier is employed for gender classification. The number of training to testing ratio was evaluated at 50 to 50, 60 to 40 and 70 to 30, to determine best classification accuracy. The data was analyzed separately of raw dataset and post-processing dataset to compare the classification results. At first, the data was classified using raw dataset and yields the classification accuracy of 93.8%. Then, the post-processing data was applied to the classifier, and it was found that the classification accuracy was improved to perfect classification on k = 5, 7, 11 and 13 to 15.

Recently, there has been an increasing concern about scientific investigations of the endogenous electromagnetic fields generated by and contained within the human body. Chakra points are defined as focal spots for reception, absorption and transmission of radiation wave of the human body. Meanwhile brain regions are defined as areas of the brain that represent the cerebrum, cerebellum and brainstem. This paper discusses on frequency characteristic of human body radiation through chakra points and brain regions. A total of 9 sites were investigated for the measurements. The readings from each site were recorded via a frequency counter. A total of 34 healthy subjects comprising of 17 males and 17 females were used in the study. Data analyses were conducted using exploratory and descriptive statistics. Results show that out of the nine sites, three were found to be significant.

Studies of potential carbon coating for high frequency microwave absorber

Hasnain Abdullah Idris; Mohd Nasir Taib; Rusnani Ariffin; Siti Zura A. Jalil; Wan Khairuddin Wan Ali

An electromagnetic (EM) wave absorber is used to absorb the reflected wave that occurs on the wall of the chamber in the anechoic chamber. To date findings show that the construction of the absorber material used for the absorbers, ferrite is in the lead. A survey on materials that can be used as a carbon for the absorber is performed and the best carbon content is a mix of wood. The absorbers are made of elephant board and then coated with carbon. The absorber is measured for 10GHz frequency. The performances of the designed absorber are compared to commercial absorbers available in terms of the absorption performance.

Gender classification using ANN based on human radiation frequencies

Mohamad Hushnie Haron; Mohd Nasir Taib; M. S. A. Megat Ali; Megawati Mohd Yunus; Siti Zura A. Jalil

This paper discusses about classification of human gender based on human frequencies of chakra points and brain regions. The main techniques used in this study are Artificial Neural Network (ANN) and k-fold cross-validation. ANN technique has been used for gender prediction and k-fold cross-validation for validation of classifier. All measurements are based on radio frequency readings. Data from 34 samples consist of 17 males and 17 females have been recorded. Three groups of points have been analyzed during classification and validation. Group 1 consists of seven chakra points and four brain regions, Group 2 consists of three chakra points and Group 3 consists of three chakra points and one brain region. The results show the variables in Group 1 are best for gender classification.

This paper presents the absorber in which it is designed and shaped to absorb incident radio frequency (RF) radiation. The absorber is designed using composite material since the significance of the project is to find a potential solution to construct a low cost anechoic chamber. This model of mini anechoic chamber, which is consisting of the new designed absorber, is portable and small in size so that it is more user friendly. The performance of the designed absorber are compared to commercial absorber available. The absorber that has been developed is a low cost absorber with the absorption rate is 16.6% less compared to the commercial absorber.

An anechoic chamber is considered good when there is no signal reflection inside the chamber and also when there is no incoming signal from outside the chamber. The key element inside an anechoic chamber is the absorbing material. The evaluations of mini anechoic chamber fitted with coated absorbers were carried out by analyzing the absorption performance. The study includes the comparison of measurement with and without coated absorbers. The evaluations were carried out using 500 MHz, 2 GHz and 10GHz frequencies. The most significant result shows an absorption level of up to approximately 75% when the chamber was fitted with coated absorbers for 10 GHz.
