T he virus are large pleomorphic spherical particles with bulbous surface pr ojections that form crown like structure and called as corona. Envelope of the virus in electron micrographs appears as a distinct pair of electron dense shells. The viral envelope consists of a lipid bilayer proteins name ly spike (S)\, envelope (E)\,membrane (M)\, and nucleocapsid (N). The S-pr otein allow the virus to attach to the membrane of the host cell. It conta ins the receptor binding domain with Angiotensin Converting Enzyme Recepto r-2 (ACE2).The E-protein is the smallest among all and inside it\, nucleoc apsid is formed to replicate all genetic information and allow to replicat e multiple copies using positive sensed single- stranded RNA. The mass of SARS-CoV-2 is ~10 -17 kg and its diameter is 80-90 nm. It gets disintegrat ed above 56˚C.\n\nExperiment performed:\nHaving known the composition of SARS-CoV-2\, it is simulated for experimentation by the closest protein av ailable. Microwave frequency of 2.45 GHz is chosen for experiments\, as cl ose to this frequency\, the absorption of microwave energy in polar molecu les (protein) is maximum. Secondly\, highly cost effective Magnetrons\, wi th varied high power\, are available at this frequency. And finally\, 2.45 GHz is internationally ISM band\, unlike other two bands of 915 MHz and 5 .2 GHz.\nFor performing experimentation\, a magnetron based microwave gene rator with following parameters were chosen: Output power = 800 watts at 2 .45 GHz and the volume of the cavity is 26 litres. This leads to power den sity inside the chamber of 0.03 watt/cc.\nSeveral experiments were perform ed adjusting the time versus weight of the protein. It was found that in 2 0 seconds with approximately 780 watt output power\, the temperature of 30 cc protein (30.9 gram with density of 1.03 gm/cc) rises to 95˚C. Microwa ve heating is volumetric\, wherein heat is generated because of friction o f polar molecules. Thus\, unlike conventional surface heating\, microwave heating is inside out. Here\, uniform and rapid heating\, ensures cent per cent efficacy.\nThough\, at 56 ˚C the virus gets disintegrated\, we went upto 95 ˚C . To further ascertain the efficacy of microwave processing\, the NMR analysis was carried out on samples of bare protein and also of mi crowaved protein. The NMR plots for protein\, before and after (untreated and treated) are analysed. It shows that the protein gets disintegrated af ter applying microwave.\nWith above experiments\, proving the efficacy of microwave power to disintegrate equivalent protein\, we designed a high po wer microwave sterilizer\, which is described in brief as follows.\n\nSyst em Description\nThe microwave sterilizer is designed and developed around 800W commercially available magnetron. The system can be divided into two broad categories\; (a) Microwave Sub-system: It consists of high power mic rowave source and an aperture matched radiator and (b) Circuitries: The ma in circuit components are\; Power supplies\, control/interlock circuits an d forced air cooling mechanism.\nThis hand held system was tested for huma n/operator safety. The radiation in the back direction is less than 0.08 m w/cm. Depending upon size and shape of various objects\, time of steriliza tion is from 1-2 minutes.\n\nShort bio of the Speaker: Dr. K. P.
