There are numerous applications for microwave absorbers in the L, S, C, X, and Ku bands. Creating a terahertz absorber, on the other hand, has proven difficult. This paper presents a metamaterial absorber operates at terahertz frequencies. It has a square shaped outer ring and a circle shaped inner ring unit cell split ring resonator. The substrate is dielectric material and the ground is metallic. According to the simulation results, the unit cell resonates at two frequencies that is at 1.3027THz and 1.7853THz with absorptivity is greater than 90% at normal incidence .The main cause of high absorbance is due to strong electromagnetic field. The proposed structure in this paper is useful for terahertz imaging, detection of malignant tumors and stealth technology.

The new outbreak of Corona virus poses a major threat and has been declared a global public health emergency. Whole World is trying to stop the virus but no efficient tool and strategy is there to control it. Monitoring of Patient’s health remotely is really important especially for patients suffering from a long-term disease. Vital signs such as pulse rate, Body temperature etc., needs to be monitored regularly as they are the primary indicators of a human’s health. Also, Elderly people gets benefited by making less visits to the hospitals for regular check-up. Therefore, we intend to bring in a GSM based health monitoring system for patient’s which provides security to patient’s health. Health monitoring is a technology to enable monitoring patient’s health outside clinical settings. The system measures the heartbeat and body temperature of patient and then the immediate information will be sent to the registered number.
